［摘要］為研究現(xiàn)澆端柱預(yù)制鋼絲網(wǎng)架聚苯夾芯混凝土墻板的抗震性能，完成了5個(gè)試件的擬靜力試驗(yàn)。試驗(yàn)結(jié)果表明：試件端柱的豎向鋼筋受拉屈服、底部混凝土壓潰；端柱水平裂縫多，墻面斜裂縫多，裂縫寬度小；水平力-位移滯回曲線飽滿；位移角達(dá)1/68時(shí)，水平力尚未下降至峰值水平力的85%；軸力作用下的正截面承載力可采用規(guī)范鋼筋混凝土剪力墻的公式計(jì)算；采用的連接方式能將預(yù)制墻板、現(xiàn)澆柱及地梁連接成整體。

Abstract:Quasi-static tests on five specimens of the pre-cast sandwich wall panel with cast-in-site end columns were carried out.The test results indicate that the vertical reinforcements of the end columns yield in tension,the bottom concrete of the end columns crush. The horizontal cracks distribute along the height of the end columns and diagonal cracks distribute on the wall panel, and the width of all cracks are narrow. The hysteretic loops of lateral force-displacement are plump. The drift ratio reaches 1/68 while the lateral force does not drop to 85% of the peak value. The code formulas of compressive strength for cast-in-site concrete walls are suitable for the pre-cast sandwich wall panel with cast-in-site end columns. The adopted connections of the specimens integrate the pre-cast wall panel, the cast-in-site column, and the foundation as an unit.

Keywords:cast-in-site end column; pre-cast sandwich wall panel; quasi-static test; seismic behavior
