Based on engineering practice and in accordance with the characteristics of the high-rise steel industrial buildings a discussion has been made on several related aspects such as building rigidity, intercolumnar brace, floor horizontal brace and joint design. 结合工程实践,针对高层钢结构工业厂房的特点,从厂房刚度、柱间支撑、楼板水平支撑及节点设计等几方面进行讨论。
Finally, a hypothesis on "three factors" of formation of solidification cracks in the intercolumnar space and joint in the arc crater region was presented. 结合理论计算提出了焊缝弧坑产生凝固裂纹的晶间空隙与连接的三因素假说。
