These are connected via additional structural members with the upper and lower sides of the main beams and equipped with additional wind bracing on the upper surface of the frame.
它们均通过主梁的首末端等附加构件连接，并在框架上表面装配附加风支柱。
The comparison between wind action only on the upper roof surface and both on the upper and lower roof surfaces, shows that the latter condition is more advantageous.
比较了仅考虑上表面风荷载作用和同时考虑上下表面风荷载作用对结构的影响，结果显示前一种情况对结构更为不利。
