摘要:
建立拱形钢结构有限元计算模型,通过数值分析的方法找出特定拱形钢结构在主拱结构刚度、主拱支座边界约束刚度、主拱使用环境温度等不同影响因素作用下主拱内力和拱支座位移的变化规律.指出温度应力是影响拱形钢结构承载能力的关键因素,并提出减少或释放温度应力的措施.
Abstract:
A finite element calculation model is established for arched steel structure. When affected by factors such as main arch’s structural stiffness, boundary restraint stiffness of support, and environmental temperature, variety laws of main arch internal force and arch support displacement were found out. Temperature stress proves to be the critical factor to the bearing capacity of arched steel structure. Measures which can reduce or release temperature stress were also suggested
