摘　　要：装配式T梁常用的纵向连接形式有竖直接缝、斜接缝、L形或阶梯形接缝以及齿块形接缝,文中主要研究斜接缝、L形接缝、齿块形接缝等三种接缝形式的构造变化对其结构力学性能的影响.分别对不同连接形式的桥梁进行有限元建模,通过改变接缝的主要构造参数,分析结构关键部位的应力和挠度,研究结构纵向连接主要参数变化对结构力学性能的影响,并通过比较得到各种连接形式的优缺点和较优结构.Vertical joints,oblique joints,L-shaped or stepped joints,and tooth block joints are commonly used for longitudinal connection of fabricated T-beams.In this paper,the influence of structural changes of oblique joint,L-shaped joint and tooth block joint on its structural mechanical properties was mainly studied.Aiming at the research object,the finite element modeling of bridges with different connection forms was carried out respectively.Then,by changing the main structural parameters of the joint,the stress and deflection of the key parts of the structure were analyzed.The influence of the main parameters of longitudinal connection on the mechanical properties of the structure was studied,and the advantages and disadvantages of various connection forms and the better structure were obtained by comparison.
