摘要:
运用ANSYS软件计算分析了双撑杆智能预应力钢桁梁跨中挠度约束范围、杆件应力约束范围、钢桁梁跨度、撑杆数量以及荷载形式5个因素对双撑杆智能预应力钢桁梁承载性能的影响,并将相同约束条件下双撑杆智能预应力钢桁梁与普通预应力钢桁梁的承载性能进行了对比.结果表明:挠度约束范围越小、应力约束范围越宽、钢桁梁跨度越大,则智能预应力钢桁梁与普通预应力钢桁梁的最大约束承载力之比就越大;双撑杆智能预应力钢桁梁的承载性能优于单撑杆智能预应力钢桁梁;智能预应力钢桁梁在逐次增多荷载工况下的承载性能优于移动集中荷载工况下的承载性能.
Abstract:
The impacts of the deflection constrain range, stress constrain range, truss span, strut number and load form on the bearing capacity of a smart prestressed steel truss with two struts were analyzed by using the ANSYS software, and the bearing capacity is compared with that of the conventional prestressed truss under the same constrain conditions. The results show that with the smaller deflection constrain range, wider stress constrain range, and longer truss span, the ratio of the constrain bearing capacity of the smart prestressed truss to that of the conventional prestressed truss is higher. The bearing capacity of the smart prestressed steel truss with two struts is better than that with single strut. The bearing capacity of the smart prestressed steel truss under the successive incremental load condition is better than that under concentrated load condition.
