项目摘要

Experiments on half scale composite steel free slabs built according to the proposed design incorporating modular permanent formwork panel made of reactive powder composite materials (RPCM) and cast-in-place fiber reinforced concrete (FRC) were performed.The results of static tests are given and the effects of loading location and support condition on different characteristic behaviors of the slabs are highlighted. Cracking strength and the developments of the cracks are described in order to demonstrate that the proposed design was able to inhibit the occurrence of wide longitudinal cracks. Stress developments in the concrete, the reactive powder materials, and the steel straps are presented and analyzed in order to verify the composite behavior of the slabs.Subsequently the carbon fiber reinforced polymers (CFRP) plates as straps instead of steel one were used and the joint performance between RPCM panel and CFRP plate was investigated.Furthermore, by based on the results of joint tests, the new steel free slabs composed of RPCM panel, FRC and CFRP straps were fabricated and static and dynamic loading tests of them were performed.The obtained results were discussed from the view points of cracking strength, development of cracks, failure modes, ultimate strength and deflection. The high ultimate punching shear strength illustrates the high capacity of the slabs and their safety under projected loading conditions.

根据提议的设计进行了由反应性粉末复合材料（RPCM）制成的模块化永久模板面板建造的一半尺度复合钢的实验，并执行了静态测试的结果。给出了静态测试的结果。负载位置和支撑条件对不同特征性行为的影响。描述了裂纹强度和裂缝的发展，以证明所提出的设计能够抑制纵向裂纹的发生。提出和分析了混凝土，反应性粉末材料和钢带的压力发展，以验证板块的复合行为。随后使用碳纤维增强聚合物（CFRP）板作为钢带而不是钢板，而不是钢板，并且使用了RPCM面板和CFRP板的均衡测试。制造了RPCM面板，FRC和CFRP皮带，并对它们进行了静态和动态载荷测试。从裂纹强度，裂缝的发展，破坏模式，最终强度和偏转的观点中讨论了获得的结果。高终极的打孔剪切强度说明了板的高容量及其在预计的装载条件下的安全性。
