| 1 | Evaluation of integration methods for hybrid simulation of complex structural systems through collapse显示文摘This study examines the performance of integration methods for hybrid simulation of large and complex structural systems in the context of structural collapse due to seismic excitations.The target application is not necessarily for real-time testing,but rather for models that involve large-scale physical sub-structures and highly nonlinear numerical models.Four case studies are presented and discussed.In the first case study,the accuracy of integration schemes including two widely used methods,namely,modified version of the implicit Newmark with fixed-number of iteration(iterative)and the operator-splitting(non-iterative)is examined through pure numerical simulations.The second case study presents the results of 10 hybrid simulations repeated with the two aforementioned integration methods considering various time steps and fixed-number of iterations for the iterative integration method.The physical sub-structure in these tests consists of a single-degree-of-freedom(SDOF)cantilever column with replaceable steel coupons that provides repeatable highlynonlinear behavior including fracture-type strength and stiffness degradations.In case study three,the implicit Newmark with fixed-number of iterations is applied for hybrid simulations of a 1:2 scale steel moment frame that includes a relatively complex nonlinear numerical substructure.Lastly,a more complex numerical substructure is considered by constructing a nonlinear computational model of a moment frame coupled to a hybrid model of a 1:2 scale steel gravity frame.The last two case studies are conducted on the same porotype structure and the selection of time steps and fixed number of iterations are closely examined in pre-test simulations.The generated unbalance forces is used as an index to track the equilibrium error and predict the accuracy and stability of the simulations. | Maikol Del Carpio R.

| 2 | 用分布式混合试验系统模拟结构的倒塌行为显示文摘采用分布式混合试验系统模拟四层钢结构框架在强震下的倒塌行为。变形集中的首层作为试验对象,而上部结构作为数值子结构。各子结构通过协调器满足界面上的平衡和协调条件,并被协调器的输入输出接口封装起来。采用柔性的试验方案,可以在当前有限控制精度的限制下,灵活地处理边界条件。试验结果与日本E-D efense振动台足尺试验结果进行了对比,得到了类似的倒塌机制,证明混合试验有能力进行结构倒塌模拟,而误差主要来自于模型简化。 | 王涛 Gilberto Mosqueda Andres Jacobsen Maria Cortes-Delgado | 2010 | 防灾减灾工程学报2010，30，S1： | 3 |
| 3 | Real-Time Hybrid Simulation of Seismically Isolated Structures with Full-Scale Bearings and Large Computational Models显示文摘Hybrid simulation can be a cost effective approach for dynamic testing of structural components at full scale while capturing the system level response through interactions with a numerical model.The dynamic response of a seismically isolated structure depends on the combined characteristics of the ground motion,bearings,and superstructure.Therefore,dynamic full-scale system level tests of isolated structures under realistic dynamic loading conditions are desirable towards a holistic validation of this earthquake protection strategy.Moreover,bearing properties and their ultimate behavior have been shown to be highly dependent on rate-of-loading and scale size effects,especially under extreme loading conditions.Few laboratory facilities can test full-scale seismic isolation bearings under prescribed displacement and/or loading protocols.The adaptation of a full-scale bearing test machine for the implementation of real-time hybrid simulation is presented here with a focus on the challenges encountered in attaining reliable simulation results for large scale dynamic tests.These advanced real-time hybrid simulations of large and complex hybrid models with several thousands of degrees of freedom are some of the first to use high performance parallel computing to rapidly execute the numerical analyses.Challenges in the experimental setup included measured forces contaminated by delay and other systematic control errors in applying desired displacements.Friction and inertial forces generated by the large-scale loading apparatus can affect the accuracy of measured force feedbacks.Reliable results from real-time hybrid simulation requires implementation of compensation algorithms and correction of these various sources of errors.Overall,this research program confirms that real-time hybrid simulation is a viable testing method to experimentally assess the behavior of full-scale isolators while capturing interactions with the numerical models of the superstructure to evaluate system level and in-structure response. | Alireza Sarebanha Andreas H.Schellenberg Matthew J.Schoettler Gilberto Mosqueda Stephen A.Mahin | 2019 | Computer Modeling in Engineering & Sciences2019，，9： | 3 |
