摘　　要：随着预应力混凝土异形截面构件在建筑结构中的广泛应用,该类结构的受力性能也受到人们的关注.本文选取工程中经常使用的T型截面混凝土悬臂构件为研究对象,以预应力度为参数,利用数值模拟方法,分析施加于T型截面悬臂构件部分区域的预应力度对构件整体受弯性能的影响.With the extensive use of the profiled elements in prestressed concrete structures, the mechanical behavior of these structures has been concerned. With the T-shaped cantilever cross-section of concrete that is often used in engineering as the research object, and prestressed degree as the parameter, this paper analyzes the prestress effect on the bending properties of T-shaped cantilever components of partially prestressed concrete by using the numerical simulation method.

关 键 词：T型构件 部分预应力 数值模拟 预应力度
