講演テーマ:Large-Scale Hybrid Testing of Steel Moment Frame Buildings through Collapse

講演概要:This paper describes two series of half-scale hybrid tests of a 4-story steel moment frame building including the gravity load resisting system.The primary objective of this research is to experimentally assess the seismic performance of a steel moment frame building from the onset of damage through collapse. A secondary objective of the experimental program is to validate a newly developed substructuring technique(Hashemi and Mosqueda,2013)used in hybrid testing of multi-story framed buildings.The physical substructures include a subassembly of the moment-resisting frame as shown in Figure 1 and a similar sized subassembly of the gravity-resisting frame. Both physical substructures were constructed with the composite concrete slab.The one and one-half story physical substructures included additional dead load on the slab at the first story level with the vertical load from the upper stories accounting for overturning forces applied through force controlled actuators.The lateral loading on the frame was applied through displacement controlled actuators commanded by the hybrid simulation algorithm.The mathematical substructures were developed using the Open System for Earthquake Engineering Simulation (OpenSees)and coupled with the Open Source Framework for Experimental Setup and Control (OpenFresco) to integrate the laboratory hardware for the hybrid simulation. The tests are being conducted at the Network for Earthquake Engineering Simulation (NEES) equipment site at University at Buffalo(UB)and are expected to be completed by early April 2013. The paper and presentation will include a detailed description of the hybrid simulation algorithms used to capture the seismic response of the structure through collapse and detailed results of these large-scale tests of moment resisting and gravity framing.
