某物资仓库拟采用框架结构和40 m跨网架屋顶。首先根据规范确定了屋顶荷载，并根据该建筑物位于台风区的实际，着重研究了风荷载的取值情况。该网架采用螺栓球节点，形式为正放四角锥形，施工采用分段整体吊装和高空散装的安装方式。实际使用情况表明，该物资库采用网架结构可靠耐用，且缩短了施工工期，取得了较好的经济效益。
某物資倉庫擬採用框架結構和40 m跨網架屋頂。首先根據規範確定瞭屋頂荷載，併根據該建築物位于檯風區的實際，著重研究瞭風荷載的取值情況。該網架採用螺栓毬節點，形式為正放四角錐形，施工採用分段整體弔裝和高空散裝的安裝方式。實際使用情況錶明，該物資庫採用網架結構可靠耐用，且縮短瞭施工工期，取得瞭較好的經濟效益。
