[提要]  進(jìn)行了無(wú)粘結(jié)預(yù)應(yīng)力板墻框架的反復(fù)荷載試驗(yàn)，對(duì)無(wú)粘結(jié)預(yù)應(yīng)力板墻框架的工作特性、無(wú)粘結(jié)預(yù)應(yīng)力筋在水平荷載下的變化規(guī)律進(jìn)行了分析。討論了墻內(nèi)配筋率與板墻框架強(qiáng)度和變形性能的關(guān)系，及其對(duì)板墻框架破壞機(jī)理的影響。
[關(guān)鍵詞]  板墻框架  無(wú)粘結(jié)預(yù)應(yīng)力  反復(fù)荷載  配筋率

Based on the experimental researches, the characteristic behavior of slab and wall frame with unbounded prestressing in the slab under low frequency cyclic loading have been studied. The effect of magnitude of reinforcement in the wall on the failure mechanism, the strength and the deformability, as well as the stress variation of the unbounded prestresslng are carefully investigated.
Keywords: slab and wall frame; unbounded prestressing; cyclic loading; magnitude of reinforcement
