体外预应力钢-轻骨料混凝土组合连续梁的有限元分析

Finite Element Analysis of External Prestressed Steel-concrete Composite Continuous Beams

主要介绍了体外预应力钢-轻骨料混凝土组合连续梁的ANSYS建模过程,并对其进行受力全过程的模拟,考虑了预应力初始阶段组合梁的受力及变形,将计算值与实际值相比较.结果表明,ANSYS能较好地模拟出体外预应力钢-混凝土组合连续梁的受力全过程.以此建立了两跨体外预应力钢-轻骨料混凝土组合连续梁模型进行模拟,分析了体外预应力钢-混凝土组合连续梁的承载力及挠度,为体外预应力钢-轻骨料混凝土组合连续梁提供了设计依据及参考.

The finite element simulation analysis of external prestressed steel-concrete composite continuous beams is presented. Taking into account the initial, it stage stress and deformation of pre-stressed composite beam, it will be calculated and compared to the actual value. The results show that, ANSYS can better simulate external prestressed steel-concrete composite continuous beam of the whole process of stress. Built two spans prestressed steel-concrete composite continuous beam model and analyzed prestressed steel-concrete composite continuous beams of deflection and bearing capacity. Reference can be provided for design and application of external prestressed steel-concrete composite continuous beam.
