［摘要］通過(guò)對(duì)一個(gè)附加角鋼的預(yù)應(yīng)力裝配框架節(jié)點(diǎn)（試件ZPJD）和一個(gè)附加阻尼器的預(yù)應(yīng)力裝配框架節(jié)點(diǎn)（試件ZPZNJD）進(jìn)行低周往復(fù)荷載試驗(yàn)，研究了試件ZPJD和試件ZPZNJD的裂縫分布、破壞形態(tài)、滯回曲線及位移延性等抗震性能。結(jié)果表明，預(yù)應(yīng)力裝配框架節(jié)點(diǎn)具有可觀的耗能能力和較強(qiáng)的變形恢復(fù)能力，并且便于震后修復(fù)，結(jié)構(gòu)整體具有良好的抗震性能，可在抗震設(shè)防區(qū)推廣和應(yīng)用。［關(guān)鍵詞］預(yù)應(yīng)力裝配框架; 節(jié)點(diǎn); 阻尼器; 抗震性能中圖分類號(hào)：TU352.11 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：1002-848X(2015)12-0058-03
Experimental study on the node of prestressed assembly frame with additional angle steels and dampersHan Jianqiang1,2, Pei Yahui1, Yang Na1, Xu Guoqiang1,2(1 College of Civil and Architectural Engineering, North China University of Science and Technology, Tangshan 063009, China; 2 Earthquake Engineering Research Center of Hebei Province, Tangshan 063009, China)Abstract: Based on low cyclic loading tests on the node of a prestressed assembly frame with additional angle steels (specimen ZPJD) and the node of a prestressed assembly frame with additional dampers (specimen ZPZNJD), seismic performances of two specimens were studied including crack distribution, failure pattern, hysteresis curve and displacement ductility. Results show that the node of the prestressed assembly frame, which has good seismic dissipation ability and deformation recovery ability, is easy to repair after the earthquake. The integrated structure has good seismic performance and can be popularized and applied in seismic precautionary zones.Keywords:prestressed assembly frame; node; damper; seismic performance
