摘　　要：开敞式钢框架不同于民用多高层建筑,没有维护墙,整个结构骨架、平台、栏杆梯子和设备等全都暴露在风的作用下。设备等质量源在空间上分布不均匀性及平台或梁错层等因素使结构动力特性更复杂。因此,该类结构静力和动力风荷载计算存在诸多不确定性。The static wind load calculation for an open steel frame supporting equipment is different from that for an enclosed building since all members of the open steel frame and the equipment are exposed in wind,and there are uncertainties in its dynamic wind load calculation due to the ununiformity of mass distribution and the irregular configuration.

关 键 词：结构设计 钢结构 风荷载 钢框架
