摘要:
针对预应力混凝土多T梁桥,基于实体退化壳单元,研究了多T梁桥极限承载力的计算方法.利用Owen屈服准则、Hinton压碎准则和双折线模型考虑了混凝土和钢筋的材料非线性效应,有效地模拟了预应力混凝土多T梁桥的开裂、屈服和失效全过程.引入实体退化壳单元理论,描述了预应力混凝土多T梁桥,其中普通钢筋和预应力钢筋采用分层单元模拟,并根据所采用的非线性理论编制了相应的非线性计算程序.结合预应力混凝土多T梁桥实桥破坏性试验资料比较可知,理论计算结果与试验数据吻合良好,研究表明用实体退化壳单元模拟预应力混凝土多T梁桥是可行的,相应的极限承载力计算方法和计算程序是正确的.
Abstract:
Based on shell element degraded from solid element, the computational method of ultimate loads of the prestressed concrete multi-T girder bridge was studied. Respectively based on Owen yielding theory and Hinton crushing theory and bilinear model, the material nonlinear properties of concrete and steel are considered. Then the process of cracking, yielding and failure of prestressed concrete multi-T girders is imitated. After the modeling of degraded shell element is introduced, the prestressed concrete multi-T girder bridge is modeled and the steel and the prestressed steel are depicted by layered shell element. The analytical procedure is compiled based on the above nonlinear theories. Compared with the failure experiment data of a prestressed concrete multi-T girder bridge, the computed results agree well. It shows that it is feasible to apply shell element degraded from solid element to depict the prestressed concrete multi-T girder bridge and the corresponding computational method and procedure for ultimate loads are correct and reliable.
