［摘要］ 為研究輕鋼龍骨混凝土組合外掛墻板的抗震性能，對(duì)兩塊足尺墻板試件進(jìn)行了低周反復(fù)荷載試驗(yàn)，得到了墻板的破壞形態(tài)及滯回曲線。試驗(yàn)結(jié)果表明：墻板破壞主要為拉板式約束節(jié)點(diǎn)處水泥纖維板的開(kāi)裂和地龍骨腹板的擴(kuò)孔，墻板與鋼框架連接節(jié)點(diǎn)區(qū)域未發(fā)生明顯破壞，說(shuō)明在該連接節(jié)點(diǎn)達(dá)到層間位移角限值時(shí)，墻板仍能保證較好的整體性，與結(jié)構(gòu)主梁之間連接可靠。未布設(shè)橫撐的輕鋼龍骨混凝土組合外掛墻板抗震性能相對(duì)較差，而布設(shè)橫撐可以提高墻板的屈服荷載及峰值荷載。兩塊墻板延性較好，能夠在罕遇地震作用下保持良好的整體性和安全性。

Abstract: Two full-scale wall specimens were tested under low cyclic loading test to study seismic behavior of light-gauge steel stud concrete composite external wall panel. The failure modes and hysteretic curves of wall panels were obtained. The experimental results indicate that failure of the wall panels is mainly caused by the cracking of fiber reinforced cementitious board and the expansion of the joint web. There is no obvious damage in the connections between the wall panel and the steel frame, which shows that wall panels can still keep in good integrity and the connection with the main beam of structure is reliable when reaching the limit value of elastic-plastic inter-story drift. Moreover, the light-gauge steel stud concrete composite external wall panel without the transverse bracing has relatively poor seismic performance. Application of transverse bracing can effectively increase the yield load and ultimate load capacity of the wall panel. Both wall panels show good ductility, and can keep integrity and safety under rare earthquake.
