（大連市建筑設(shè)計(jì)研究院有限公司，大連 116021）[摘要] 車庫(kù)入口作為人防的主要出入口時(shí)，其門框墻上擋墻承受較大的爆炸水平荷載，采用規(guī)范的計(jì)算方法得到的配筋結(jié)果很大，甚至出現(xiàn)超筋現(xiàn)象。將上擋墻中部的次梁作為上擋墻下部橫梁的支座，減小其計(jì)算跨度，得到了經(jīng)濟(jì)合理且滿足設(shè)計(jì)要求的結(jié)果。[關(guān)鍵詞] 人防工程；地下車庫(kù)；主要出入口；門框墻中圖分類號(hào)：TU93+3 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：1002-848X(2013)S2-0129-03Calculation method of the doorframe wall under the secondary beam as supportLiu Jianqiang, Wang Jinlai(Dalian Architectural Design & Research Co., Ltd, Dalian 116021,China)Abstract: When the garage entrance is the main entrance to the civil air defence basement, doorframe wall affords the large horizontal load explosion. Using the standard method, the reinforcing bars of the doorframe wall is great or out of the bounds.
