［摘要］對鋼絲網(wǎng)架水泥細(xì)石夾芯板的水平承載力進(jìn)行了試驗(yàn)研究。通過對4個(gè)不同的試驗(yàn)構(gòu)件進(jìn)行往復(fù)加載試驗(yàn)，考察了開洞及連接構(gòu)造對板材受力性能及破壞模式的影響。試驗(yàn)結(jié)果表明，在連接構(gòu)造可靠的情況下，鋼絲網(wǎng)架水泥細(xì)石夾芯板可充分發(fā)揮水平承載力，具有較好的受力性能。最后在試驗(yàn)基礎(chǔ)上提出了鋼絲網(wǎng)架水泥細(xì)石夾芯板的水平承載力及初始剛度的簡化計(jì)算方法。

Abstract:Experiment study on load capacity of the prefabricated steel-mesh cement infilled panels was presented. Through the cyclic loading test on 4 specimens, effects of hole and connection details on the panels mechanical behavior and failure mode had been studied. The experimental results suggest that if the connection details are reliable, the prefabricated steel-mesh cement infilled panels can provide satisfied load capacity. Based on the experimental results, a simplified calculation method to calculate the load capacity and initial stiffness of the prefabricated steel-mesh cement infilled panels was proposed.

Keywords:steel structure; prefabricated steel-mesh cement infilled panels; cyclic load; initial stiffness; load capacity
