摘　　要：基于数值拟合的滞回曲线和骨架曲线模型,运用增量动力分析法,对结构进行了国内外20条地震记录作用下的动力分析,研究了轻钢龙骨房屋的抗震性能。研究结果表明:轻钢龙骨房屋结构具有承载力高、延性适中、抗震性能好等优点,能够作为普通住宅结构运用于我国广大的抗震设防地区。The paper analyzed the dynamic performance of the structure under the 20 kinds of earthquakes using the Incremental Dynamic Analysis method with the numerical model of the hysteretic curve and the skeleton curve, and studies the seismic performance of the light-gauge steel framed residence. The results showed that the light-gauge steel framed residence structures have the advantages of high beating capacity, moderate ductility and good seismic behavior. They can be used as the common residence structures in most earthquake resistance area of China.
