到目前为止，日本、美国和欧洲已经在受控实验室条件下用模拟地震荷载对全尺寸建筑系统进行了测试，以确定行为和设计极限状态，并校准预测分析和设计模型。这些测试的地震荷载模拟包括增加循环荷载/变形模式，并具有预定的荷载分布，或在可能的情况下，根据实测建筑物响应以及通过伪动态测试更新的位移时程，通过实验得出的荷载模式。通过对美国第一个5层钢筋混凝土结构全尺寸试验中的试验硬件和作动器控制算法的创新，解决了由于作动器之间的紧耦合、数值积分算法的稳定性问题、测量误差和误差增长以及不良扭转模态的控制等问题。
Full-scale building systems have been tested to-date in Japan, the United States, and Europe under controlled laboratory conditions with simulated seismic loads, to determine behavior and design limit states and to calibrate predictive analytical and design models. Seismic load simulation for these tests consisted of increasing cyclic load/deformation patterns with predetermined load distribution or, where possible, of loading patterns derived experimentally from the measured building response in conjunction with updated displacement time-histories through pseudo-dynamic testing. Difficulties in the pseudo-dynamic testing of stiff multi-story buildings due to the tight coupling between individual actuators, stability problems with the numerical integration alorithms, measurement errors and error growth, as well as the control of undesirable torsional modes, were addressed with innovations in the testing hardware and in the actuator control alorithms in the first US full-scale building test of a 5-story reinforced masonry building.
