摘　　要：建筑的抗震性能与结构形式息息相关,研究异形柱框架对复合墙板的抗震性能影响十分必要。本课题提出一种城镇建筑适用的装配式复合墙板,采用湿连接形成整体框架,其外边框与现浇构造柱、叠合梁共同形成装配整体式异形柱框架结构体系:设计并制作了无异形柱和有T形异形柱的两块复合墙板1∶2缩尺模型,通过拟静力试验,研究其破坏机理和抗震性能。研究表明:两块墙板皆呈剪切破坏,但其破坏原因不同,无异形柱框架的复合墙板因外边框柱脚严重破坏而结束试验,带T形异形柱框架的复合墙板则因异形柱框架无法继续工作而结束试验;带T形异形柱框架的复合墙板耗能能力要优于无异形柱框架的复合墙板,其承载力和变形能力也更优。The seismic performance of the building is closely related to the structural form,so it is necessary to study the effect of shaped column frame on the seismic performance of composite wall panels.This topic proposes an assembled composite wall panel applicable to urban buildings,which adopts wet connection to form an integral frame,and its outer frame together with cast-in-place structural columns and stacked beams form an assembled integral shaped-column frame structural system.Two composite wall panels without shaped columns and with T-shaped shaped columns are designed and fabricated as 1∶2 scaled models,and their damage mechanisms and seismic performance are investigated through proposed static tests.The study shows that both wall panels are damaged in shear,but the causes of damage are different:the composite wall panel without shaped column frame ends the test due to the serious damage of the outer frame footing,while the composite wall panel with T-shaped shaped column frame ends the test due to the inability of the shaped column frame to continue to work;the energy consumption capacity of the composite wall panel with T-shape shaped column frame is better than that of the composite wall panel without shaped column frame,and its load carrying capacity and deformation capacity are better as well.
