China coastal area is an important area for national economy and social development in our nation, coastal area is in joint zone of continent and sea, so geological environment is very weak. 摘要沿海地区是我国国民经济和社会发展的重要地区,又处于大陆与海洋交汇地带,地质环境比较脆弱。
Investigation of Microstructure and Stress Distribution of the Fe_3Al Joint Zone(JZ) by Fusion Welding Fe3Al熔焊接头区组织结构及应力分布研究
The formula calculating the initial stiffness of welded connection of steel frame was drawn according to bending deformation mechanism of joint zone of welded steel frame. 先从梁柱节点受弯变形的机理入手,推导出钢框架梁柱焊接连接节点的初始刚度计算公式。
The bonding strength of joint zone made by direct and indirect bonding was evaluated and their fracture characteristics were analysed. 对直接连接和间接连接接头的接合强度进行了评估,并对接头断裂特性进行了分析。
Carrying out simulated analysis behavior of joint when monotonic loading on the top surface of column and beam, the stress distribution of concrete and steel tube and steel bar in joint zone and Concrete Filled Square Steel Tubular column were obtained. 模拟分析了对柱顶单调加载和对梁加载时的受力性能,得出了节点区和方钢管柱的混凝土、钢管、钢筋的应力分布。
