摘要
以既有公路上跨新建桥梁悬浇连续梁施工为例,对梁体钢筋混凝土立柱临时支撑的力学性能进行了有限元分析,同时分析了荷载偏心情况下立柱的应力变化情况,以此探究立柱在荷载偏心情况下的安全性和稳定性,并给出了保障安全的一些合理化建议。
This paper took the construction of a continuous beam cast-in-place on a newly built bridge over an existing highway as an example,carried out a finite element analysis on the mechanical properties of the temporary support of the reinforced concrete column of the beam body,and analyzed the stress change of the column under the condition of eccentric load,for exploring the safety and stability of the column under eccentric load,and offered some reasonable suggestions to ensure safety.
