摘要: 人防工程的净空要求是影响平战结合的突出问题,现有设计存在造价较高且施工不便等缺点。通过介绍钢–连续纤维复合筋(Steel-FRP Composite Bar,简称SFCB)和活性粉末混凝土(Reactive Powder Concrete,简称RPC)的材料特性,推算两种材料的强度设计值及材料提高系数,为人防工程设计中采用SRCB和RPC提供了理论依据。结合实际工程,就框架梁采用传统的HRB400级钢筋和C40级混凝土同采用SFCB和RPC进行配筋和截面的对比,结果表明:在梁宽和配筋不变的条件下,新材料可以有效减小梁高。SFCB和RPC这两种高新材料的结合,在人防工程中具有良好应用价值。
Abstract: The clearance requirement of civil defense engineering is a critical factor affecting the integration of peacetime and wartime functions. Current design schemes often result in high construction costs and reduced constructability. This study introduces the material properties of Steel-FRP Composite Bar (SFCB) and Reactive Powder Concrete (RPC), and calculates their design strength values and enhancement coefficients, providing a theoretical basis for the application of SFCB and RPC in civil defense engineering. Based on a practical project, a comparative analysis is conducted on frame beams reinforced with conventional HRB400 steel bar and C40 concrete versus beams using SFCB and RPC. The results show that, under identical beam width and reinforcement conditions, the use of these new materials can effectively reduce beam height. The combination of SFCB and RPC demonstrates promising applicability and engineering value in civil defense structures.
