      型钢自密实混凝土叠合剪力墙延性性能试验分析

      Experiment and analysis on ductility behavior of SCC composite shear walls with profile steel

      摘要:
      为了研究影响型钢自密实混凝土(SCC)叠合剪力墙延性性能的因素,对1个全现浇型钢混凝土剪力墙试件和5个型钢SCC叠合剪力墙试件进行低周反复加载试验.在试验的基础上,利用平截面假定,提出型钢SCC叠合剪力墙屈服位移、极限位移和位移延性系数的计算公式.结果表明:型钢SCC叠合剪力墙的延性性能与全现浇型钢混凝土剪力墙相差不大;选择截面面积较大的型钢并将其以翼缘平行于预制板的方式布置于暗柱内,以及在型钢表面焊接栓钉,均可提高型钢SCC叠合剪力墙的延性;提出的计算方法合理可靠,计算结果与试验值吻合较好.
      Abstract:
      In order to study the ductility capacity of self compacting concrete (SCC) composite shear walls with profile steel,a quasi-static test was carried out on one steel reinforced concrete shear wall and five SCC composite shear walls with profile steel.On the basis of experiment,a calculation method of yield displacement,ultimate displacement and displacement ductility coefficient was proposed in this paper by using plane section assumption.The results show that the ductility capacity of SCC composite shear walls with profile steel is similar to steel reinforced concrete shear walls.There are two approaches to improve the ductility capacity of SCC composite shear walls with profile steel:one is to choose a bigger profile steel and to place it in the concealed column with its flange parallel to component panel,the other is to wield studs on the profile steel.The reliability of the method is certified by its result,which has been proved consistent with the experiment value.
