The bearing capacity of the building is calculated from experimental capacity curves of the individual walls idealized with bilinear elastic-perfectly plastic curves. The experimental capacity curves were obtained from in-plane cyclic loading tests on unreinforced and strengthened masonry walls with reinforced concrete jackets. The seismic action is compared with the load-bearing capacity of the building considering non-linear material behavior with its post-peak capacity.

A significant reduction of the seismically induced loads can be obtained by the application of base isolation systems, which have to be designed carefully with respect to the modified hydrodynamic behaviour of the tank in interaction with the liquid. For this reason a highly sophisticated fluid-structure interaction model has to be applied for a realistic simulation of the overall dynamic system. In the following, such a model is presented and compared with the results of simplified mathematical models for rigidly supported tanks.

We demonstrate in this paper, that the application of simple, periodic techniques to realistic media, that are just close to periodic, gives accurate, approximative solutions. In order to obtain effective parameters for the homogenized heat equation, we have to solve a so called "cell problem". In contrast to periodic structures it is not trivial to determine a suitable unit cell, which represents a non-periodic media. To overcome this problem, we give a rule of thumb on how to choose a good cell.

The prediction of reservoir temperature and production behavior is crucial for success of the proposed geothermal doublet. This work presents the results of a study of the important geothermal and geohydrological issues for the doublet design. In the first phase of the study, the influences of the three-dimensional (3D) structures of anticlines and synclines on the temperature field were examined. A comprehensive petrophysical investigation was performed to build a large scale 3D-model of the reservoir. Several bottomhole temperatures (BHTs), as well as petrophysical logs were used to calibrate the model using thermal conductivity measurements on 50 samples from boreholes in different lithological units in the study area. Profiles and cross sections extracted from the calculated temperature field were used to study the temperature in the surrounding areas of the planned doublet. In the second phase of the project, a detailed 3D numerical reservoir model was set up, with the aim of predicting the evolution of the producer and injector temperatures, and the extent of the cooled area around the injector. The temperature model from the first phase provided the boundary conditions for the reservoir model. Hydraulic parameters for the target horizons, such as porosity and permeability, were taken from data available from the nearby exploration wells. The simulation results are encouraging as no significant thermal breakthrough is predicted. For the originally planned location of the producer, the extracted water temperature is predicted to be around 79 °C, with an almost negligible cooling in the first 50 years of production. When the producer is located shallower parts of the reservoir, the yield water temperatures is lower, starting at ≈76 °C and decreasing to ≈74 °C after 50 years of operation. This comparatively larger decrease in temperature with time is caused by the structural feature of the reservoir, namely a higher dip causes the cooler water to easily move downward. In view of the poor reservoir data, the reservoir simulation model is constructed to allow iterative updates using data assimilation during planned drilling, testing, and production phases. Measurements during an 8 h pumping test carried out in late 2010 suggest that a flow rate of 150 m3 h-1 is achievable. Fluid temperatures of 76.5 °C were measured, which is very close to the predicted value.}, language = {en} } @incollection{BorchertHeimannSchemm2011, author = {Borchert, J{\"o}rg and Heimann, Thorsten and Schemm, Ralf}, title = {Speicheroptimierung}, series = {Gashandel und Gasbeschaffung}, booktitle = {Gashandel und Gasbeschaffung}, publisher = {Euroforum Verl.}, address = {D{\"u}sseldorf}, publisher = {Fachhochschule Aachen}, pages = {1 -- 69}, year = {2011}, abstract = {In dieser Lektion wurden beginnend mit der Darstellung des fundamentalen Wandels des Gasmarktes die daraus folgenden Implikationen f{\"u}r die Einsatzweise von Gasspeichern abgeleitet. Anschließend wurden zwei Bewertungs- und Steuerungsverfahren f{\"u}r einen Gasspeicher an den beiden Marktstufen Termin- und Spotmarkt methodisch vorgestellt und anhand von Beispielrechnungen illustriert. Das Verfahren zur Bewertung und Steuerung im Terminmarkt stellt ein sehr robustes und methodisch einfaches Verfahren dar. Hierbei wird die Saisonalit{\"a}t der Forwardkurve bzw. deren Ver{\"a}nderungen arbitragefrei mithilfe des Speichers ausgenutzt. Dieses Verfahren kann nicht den gesamten Zeitwert des Speichers ausweisen. Es zieht in jedem Zeitpunkt nur die aktuellen Informationen der Forwardkurve zur Entscheidung heran. Es bildet aber keine bedingte Erwartung {\"u}ber zuk{\"u}nftige Ertr{\"a}ge und deren Beeinflussung durch die aktuelle Speicherfahrweise, um hieraus eine optimale Entscheidung zu formulieren. Bei der Bewertung gegen{\"u}ber dem Spotmarkt mithilfe der Least-Squares-Monte- Carlo-Simulation wird in einer stochastischen Optimierung dagegen der volle Zeitwert des Speichers und damit der gesamte Zusatznutzen der Flexibilit{\"a}t ermittelt. Hierdurch leiten sich auch wesentlich andere Hedging-Empfehlungen als im ersten Verfahren ab, um diesen zu sichern. Der Einsatz der beiden Verfahren im Alltag zur Bewirtschaftung des Speichers h{\"a}ngt insbesondere vom Know-how, den Speicherparametern und der Risikobereitschaft des Handels ab. Beide Strategien liefern hierzu Hedging-Empfehlungen ab, mit welchem der zugrunde liegende Wert gesichert werden kann. Risikoaverse H{\"a}ndler, die einen Großteil des inneren Wertes sichern wollen, k{\"o}nnten im Terminmarkt einen Großteil des Speichers mithilfe des „Intrinsic Rolling"-Verfahrens bewirtschaften. Sie w{\"u}rden hierdurch den saisonalen Spread in der Forwardkurve rollierend sichern. Gleichzeitig kann ein kleinerer Anteil mithilfe der stochastischen Optimierung und den damit verbundenen Aus{\"u}bungsgrenzen gegen{\"u}ber dem Spotmarkt bewirtschaftet werden. In einem liquiden vollst{\"a}ndigen Markt wird eine Steuerung des Speichers allein gegen{\"u}ber den vorhandenen Marktstufen vorgenommen und der Wert f{\"u}r alle Marktteilnehmer objektiv messbar. F{\"u}r den Fall, dass der Markt illiquide ist und hierdurch z. B. eine Kundenlast nicht allein am Termin- und Spotmarkt jederzeit gedeckt werden kann, erscheint es notwendig, den Speicher im Kontext einer Portfoliooptimierung zu bewerten. Dies wird in der n{\"a}chsten Lektion vorgenommen. Hierbei ist aber zu beachten, dass der Speicher dadurch eine individualisierte Wertkomponente erh{\"a}lt, die von der konkreten Ausgestaltung des jeweiligen Portfolios abh{\"a}ngt.}, language = {de} } @incollection{MeskourisNordaButenweg2011, author = {Meskouris, Konstantin and Norda, Hannah and Butenweg, Christoph}, title = {Aktuelle Nachweiskonzepte von Mauerwerk unter Erdbebenbeanspruchung}, series = {Wie wollen wir in Zukunft bauen? : Festschrift zum 60.

In particular, it allows to numerically treat systems in which a laser field interacts with the medium with both its electric and magnetic component at the same time. The internal dynamics of the few-level system is modeled by a quantum optical master equation which includes coherent processes due to optical transitions driven by the laser fields as well as incoherent processes due to decay and dephasing. The propagation dynamics of the laser fields is treated in slowly varying envelope approximation resulting in a first order wave equation for each laser field envelope function. The program employs an Adams predictor formula second order in time to integrate the quantum optical master equation and a Lax-Wendroff scheme second order in space and time to evolve the wave equations for the fields. The source function in the Lax-Wendroff scheme is specifically adapted to allow taking into account the simultaneous coupling of a laser field to the polarization and the magnetization of the medium. To reduce execution time, a customized data structure is implemented and explained. In three examples the features of the program are demonstrated and the treatment of a system with a phase-dependent cross coupling of the electric and magnetic field component of a laser field is shown.}, language = {en} } @book{MeskourisHinzenButenwegetal.2011, author = {Meskouris, Konstantin and Hinzen, Klaus-G{\"u}nter and Butenweg, Christoph and Mistler, Michael}, title = {Bauwerke und Erdbeben : Grundlagen - Anwendung - Beispiele. - 3., aktualisierte und erweiterte Auflage}, edition = {3., aktualisierte und erweiterte Auflage}, publisher = {Vieweg + Teubner}, address = {Wiesbaden}, isbn = {978-3-8348-9856-2 (E-Book) ; 978-3-8348-0779-3 (Print)}, doi = {10.1007/978-3-8348-9856-2}, pages = {XVIII, 718 S.}, year = {2011}, language = {de} } @inproceedings{MeskourisHoltschoppenButenwegetal.2011, author = {Meskouris, Konstantin and Holtschoppen, Britta and Butenweg, Christoph and Rosin, Julia}, title = {Seismic analysis of liquid storage tanks}, series = {Earthquake Geology and Archaeology: Science, Society and Critical facilities : proceedings ; 2nd INQUA-IGCP 567 International Workshop on Active Tectonics, Earthquake Geology, Archaeology and Engineering ; 19-24 September 2011, Corinth (Greece) / Eds.: C.

We gave an existence and uniqueness proof for the weak solution of the reformulated problem. To obtain a numerical solution, we developed a semi-implicit and a fully implicit finite volume method.

To this end, we apply a stochastic modelling sequence, a Monte Carlo study, based on (i) creating an ensemble of possible realizations of a reservoir model, (ii) forward simulation of fluid flow and heat transport, and (iii) constraining post-processing using observed state variables. To generate the ensemble, we use the stochastic algorithm of Sequential Gaussian Simulation and test its potential fitting rock properties, such as thermal conductivity and permeability, of a synthetic reference model and—performing a corresponding forward simulation—state variables such as temperature. The ensemble yields probability distributions of rock properties and state variables at any location inside the reservoir. In addition, we perform a constraining post-processing in order to minimize the uncertainty of the obtained distributions by conditioning the ensemble to observed state variables, in this case temperature. This constraining post-processing works particularly well on systems dominated by fluid flow. The stochastic modelling sequence is applied to a large, steady-state 3-D heat flow model of a reservoir in The Hague, Netherlands. The spatial thermal conductivity distribution is simulated stochastically based on available logging data. Errors of bottom-hole temperatures provide thresholds for the constraining technique performed afterwards. This reduce the temperature uncertainty for the proposed target location significantly from 25 to 12 K (full distribution width) in a depth of 2300 m. Assuming a Gaussian shape of the temperature distribution, the standard deviation is 1.8 K. To allow a more comprehensive approach to quantify uncertainty, we also implement the stochastic simulation of boundary conditions and demonstrate this for the basal specific heat flow in the reservoir of The Hague. As expected, this results in a larger distribution width and hence, a larger, but more realistic uncertainty estimate. However, applying the constraining post-processing the uncertainty is again reduced to the level of the post-processing without stochastic boundary simulation. Thus, constraining post-processing is a suitable tool for reducing uncertainty estimates by observed state variables.}, language = {en} } @inproceedings{GellertParkButenweg2010, author = {Gellert, Christoph and Park, Jin and Butenweg, Christoph}, title = {Seismic safety verification of masonry structures}, series = {Proceedings of the Eight International Masonry Conference : held in Dresden from 4th to 7th of July 2010 / [International Masonry Society ; Technische Universit{\"a}t Dresden].

This study explores the suitability of acoustic cardiac triggering (ACT) for left ventricular (LV) function assessment in healthy subjects (n=14). Methods: Quantitative analysis of 2D CINE steady-state free precession (SSFP) images was conducted to compare ACT's performance with vector ECG (VCG). Endocardial border sharpness (EBS) was examined paralleled by quantitative LV function assessment. Results: Unlike VCG, ACT provided signal traces free of interference from EMF or MHD effects. In the case of correct Rwave recognition, VCG-triggered 2D CINE SSFP was immune to cardiac motion effects—even at 3.0 T. However, VCG-triggered 2D SSFP CINE imaging was prone to cardiac motion and EBS degradation if R-wave misregistration occurred. ACT-triggered acquisitions yielded LV parameters (end-diastolic volume (EDV), endsystolic volume (ESV), stroke volume (SV), ejection fraction (EF) and left ventricular mass (LVM)) comparable with those derived fromVCG-triggered acquisitions (1.5 T: ESVVCG=(56± 17) ml, EDVVCG=(151±32)ml, LVMVCG=(97±27) g, SVVCG=(94± 19)ml, EFVCG=(63±5)\% cf.
