The semi-rigid nodes of the end-plate connection and the bolt prestress were respectively simulated by the contact element and prestress element based on the presentation of forms the end-plate connection and performance of forces.
门式刚架中普遍采用的端板类连接是典型的半刚性节点连接,在介绍门式刚架端板节点的形式及其受力性能的基础上,采用接触单元来模拟端板连接节点的半刚性,预应力单元来模拟螺栓的预拉力,利用ANSYS软件对门式刚架半刚接节点进行了非线性有限元分析,深入分析了半刚性节点中加劲肋、端板厚度、螺栓直径变化对其性能的影响。
Grade 650 and grade 800 cold-rolled ribbed bars are developed according to the demand of the medium and small-sized prestressed members in China, their elongation is equal to that of high-strength carbon steel and they are appropriate steel for small and medium-sized prestresseed m.
我国冷轧带肋钢筋国家标准中的 ５５０级钢筋的力学性能指标与国际标准相当，钢材质量在采用专用盘条生产后能大幅度提高；６５０级和８００级冷轧带肋钢筋是根据国内中小预应力构件的需要自行开发的，其延性与高强碳素钢丝相当，是中小预应力构件的适用钢材。
