做了三榀两跨框支墙梁1/2比例模型试验;对模型在竖向及反复水平荷载作用下的破坏过程、破坏机理和水平承载力等进行了分析;根据试验与分析结果,论述了这种结构的抗震性能. A 1/2-scale model test of a three-span, two-span, box-supported wall beam was performed; the failure process, failure mechanism, and horizontal bearing capacity of the model under vertical and repeated horizontal loads were analyzed; based on the results of the test and analysis, The seismic performance of this structure.
