［摘要］對(duì)兩種由鍍鉻C型鋼做骨架、聚苯乙烯顆粒填充熱塑壓軋而成的鋼塑復(fù)合板（其中A類板件規(guī)格為3 650mm×2 395mm ×140mm（長(zhǎng)×寬×厚），B類板件是在A類板件的內(nèi)外側(cè)表面增加厚度為10mm的硅酸鈣板）進(jìn)行了低周往復(fù)水平加載試驗(yàn)，分別研究其承載力、變形能力、滯回特性等方面性能。試驗(yàn)結(jié)果表明，兩種板件均具備一定的側(cè)向承載力，其中B類板件的水平極限承載力更高；兩者變形性能均較好，兩種板件均展現(xiàn)了良好的耗能能力，能滿足作為非承重垂直分隔構(gòu)件的要求，符合抗震設(shè)計(jì)的延性要求。試驗(yàn)結(jié)果可為裝配式結(jié)構(gòu)墻體在設(shè)計(jì)和施工方面提供參考。

Abstract:The low-cycle reciprocating horizontal loading tests were carried out respectively for 2 kinds of steel-plastic structure composite plate with chromium plating C-shaped steel as skeleton, filled with thermoplastic rolling polystyrene particles, wherein type-A plate has specifications for 3650mm×2395mm×140mm (length×width×thickness) and type-B plate has additional 10mm-thick calcium silicate plates at the inner and outer sides of the type-A plate. The performance of the bearing capacity, deformation ability and hysteresis characteristics was studied. The test results show that both kinds of plates have a certain lateral bearing capacity, while type-B plate has higher  horizontal ultimate bearing capacity. Both plates show good abilities for deformation and energy dissipation, which can meet the requirements as non-load-bearing vertical separator members, and match with the ductility requirements of seismic design. The test results provide  reference for the design and construction of the prefabricated structural walls.

Keywords:light-steel prefabricated structure; steel-plastic composite plate; quasi-static test; seismic performance; interior and exterior walls
