［提要］Ⅲ級(jí)以下鋼筋在人防結(jié)構(gòu)設(shè)計(jì)中暴露出了結(jié)構(gòu)構(gòu)件鋼筋用量偏多、造價(jià)較高且施工

不便等缺點(diǎn)。結(jié)合人防工程設(shè)計(jì)中的實(shí)際問(wèn)題，從分析人防工程的特點(diǎn)入手，得出了在人防工程設(shè)計(jì)領(lǐng)域推廣HRB500高強(qiáng)度鋼筋的優(yōu)勢(shì)，并就現(xiàn)行人防設(shè)計(jì)規(guī)范所不具備的設(shè)計(jì)參數(shù)進(jìn)行了推算，為今后在人防工程設(shè)計(jì)中采用HRB500鋼筋提供了理論依據(jù)。結(jié)合實(shí)際工程，就采用傳統(tǒng)的HRB400鋼筋同采用新型的HRB500鋼筋在經(jīng)濟(jì)性上進(jìn)行了對(duì)比，得出HRB500高強(qiáng)度鋼筋應(yīng)用于人防結(jié)構(gòu)設(shè)計(jì)有很多有利因素，具有較大的推廣價(jià)值。

Foreground Discussion on HRB500 Reinforcement Applied in Civil Air Defence Structures/Pei Zhi1, Zhang Lei2, Li Yufeng2, Sui Shuqian1 (1 Shandong Architecture Design Institute, Jinan 250001, China; 2 Jinan Air Defence Architectural Designand Research Institute, Jinan 250014, China)

Abstract:In the civil air defence works engineering, the traditional steel products have exposed many defects, such as the huge quantity of reinforcement, the inconvenience in construction, and so on. With view to the characteristics and the practical problems in the design of the civil air defence works, the advantages of the use of high strength reinforcement are introduced, and theoretical proofs are presented on the base of calculation with parameters beyond the design code. Then economic contrast of the use of HRB400 and new HRB500 reinforcement is given as well. Finally, a conclusion is obtained that the use of high strength reinforcement in air defence works has many advantages in the technical and economic fields and is worth of being wildly generalized.
