［摘要］提出一種由新型預(yù)應(yīng)力空心板和后澆邊緣構(gòu)件組成的新型裝配式樓蓋。對(duì)試件模型進(jìn)行單向反復(fù)加載試驗(yàn)，分析其平面內(nèi)受力性能，并計(jì)算出樓蓋的平面內(nèi)剛度。由此討論新型裝配式樓蓋是否具有替代整體現(xiàn)澆樓蓋或帶有現(xiàn)澆面層的普通裝配式樓蓋的可行性。結(jié)果表明，新型裝配式樓蓋的平面內(nèi)受力性能良好，計(jì)算得出的平面內(nèi)剛度比一般裝配式樓蓋的平面內(nèi)剛度大6倍左右，新型裝配式樓蓋具有更大的平面內(nèi)剛度和良好的結(jié)構(gòu)整體性，新型裝配式樓蓋具有替代整體現(xiàn)澆樓蓋或帶有現(xiàn)澆面層的普通裝配式樓蓋的可行性。［關(guān)鍵詞］裝配整體式樓蓋; 相對(duì)水平撓度; 平面內(nèi)剛度; 整體工作性能中圖分類號(hào)：TU398+.2 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：1002-848X(2016)10-0050-06
Experimental study on in-plane rigidity of new-type prefabricated floorLi Qingning, Ge Lei, Han Chun, Jiang Weishan(School of Civil Engineering, Xi'an University of Architecture and Technology, Xi'an 710055, China)Abstract: A new-type prefabricated floor composed of a new-type prestressed hollow slab and post-poured edge members was put forward. The in-plane mechanical feature and in-plane rigidity were analyzed and calculated through the unidirectional repeated loading test on specimen model. Based on the test results, it can be discussed that whether the new-type prefabricated floor can take the place of integral cast-in-situ floor or ordinary prefabricated floor with cast-in-situ surface. The results show that the in-plane mechanical feature of the new-type prefabricated floor is good and the calculated in-plane rigidity is about six times larger than ordinary prefabricated floor. The new-type prefabricated floor has larger in-plane rigidity and favorable structural integrity. The new-type prefabricated floor has the possibility of taking the place of integral cast-in-situ floor or ordinary prefabricated floor with cast-in-situ surface.Keywords: prefabricated monolithic floor; relative horizontal deflection; in-plane rigidity; integral working performance
