摘　　要：为研究预应力混凝土双T板在实际工程中的受力变形情况,按照受弯预制构件结构性能检验的要求,进行了现场结构性能试验,得到了荷载-跨中挠度曲线。利用有限元分析软件ABAQUS模拟现场试验,探究了双T板变形发展的全过程。将有限元数值模拟得到的荷载-跨中挠度曲线与试验值进行比较,结果表明:有限元计算的荷载-跨中挠度曲线在弹性阶段与试验值基本吻合,该有限元模拟方法较可靠。在有限条件下,数值模拟的方法可以作为双T板结构性能检测的补充。In order to study the stress and deformation of precast prestressed concrete double-T slab in practical engineering,according to the requirements of structural performance test of flexural precast members,the field structural performance test is carried out,and the load mid span deflection curve is obtained.Using the finite element analysis software ABAQUS to simulate the field test,the whole process of deformation development of double-T plate is explored.The load mid span deflection curve obtained by finite element numerical simulation is compared with the test value.The results show that the load mid span deflection curve calculated by finite element is basically consistent with the test value in the elastic stage,and the finite element simulation method is more reliable.Under limited conditions,the numerical simulation method can be used as a supplement to the performance test of double T-plate structure.
