- Its test specimens are 8 r . c hollow shear wall compression members which have different ratio of length to effective depth of section , 3 bend - shear members and 4 different section shear walls
本文试验的对象为8个不同长细比的轴心受压构件、 3个弯剪构件和4个整体空心剪力墙板。 - Modeling the general solid web continuous box girder and opening - in - web ( open web ) continuous box girder by ansys finite element modeling tool , node stress of governing section and corresponding shear lag values are analyzed . the solution is validated by comparing with variational results and modeling test values . based on the model , the section shear lag induced by dead load , prestress tendons and car loads under the most unfavorable condition and lateral symmetry are also approached . the influence of shear lag effect in double - level continuous box girder is considered with opening - in - web and the web location . the analysis indicates that double - level - load arouses less shear lag effect than one - level - load . when self - weight and prestressed tendons act on together , the shear lag effect on box girder take on a evidently change
基于所建立的有限元模型，本文分别对实腹和腹板开孔两种箱梁在恒载、车载、预应力荷载作用时，各主要截面的剪力滞效应进行分析，通过施加纵向最不利的和横向对称的车辆荷载，研究实腹连续箱梁和空腹连续箱梁在承受双层荷载和单层荷载时引起的剪力滞效应，并考虑腹板开孔及开孔位置对于连续箱梁剪力滞效应的影响。分析表明，双层车载对于箱梁引起的剪力滞系数比单层车载的影响要小，对于箱梁中存在引起的剪力滞后现象有一定的改善作用。 - According to the new concrete code , the calculation formula are put forward concerning the load - carrying capacity during construction , the load - carrying capacity of cross - section bending , longitudinal shearing , the inclined - section shearing and part shearing during the application of the continuous composite floor slab , which provide the design proofs for the continuous composite floor slab
