摘要
利用ABAQUS有限元软件模拟火灾作用下预应力混凝土双T板的温度场及变形,获得了在耐火极限规定时间下的截面温度分布及挠度发展过程,分析了预应力混凝土双T板在高温条件下的受力性能,得出了其不满足耐火极限要求的结论,提出了在工程实践中的改善措施。
It uses the ABAQUS finite element simulation analysis software to simulate the temperature filed and distortion of prestressed concrete double T board under fire,obtains the temperature distribution of section and the deflection development during the limited fire-endurance time,analyzes the mechanical properties of prestressed concrete components under high temperature,indicates that the double T board does not meet the fire resistance requirements and put forward improvement measures in the engineering practice.
