超高性能混凝土华夫板受力性能试验研究与数值模拟OA北大核心CSTPCD
Experimental and numerical investigations on mechanical performance of UHPC waffle panels
超高性能混凝土(ultra-high performance concrete,UHPC)华夫板具有质量轻、刚度大、承载能力高等优点,在大跨度桥梁桥面板和建筑楼屋盖等工程中有良好的应用前景.通过4块UHPC华夫板1∶2缩尺模型的静力加载试验,研究了四点和四边支承边界条件、不同横肋间距下UHPC华夫板的抗裂性能、刚度、承载能力和受力机制.采用ABAQUS建立精细有限元模型,进一步研究了纵横肋受拉钢筋配筋率、纵横肋分布、顶板厚度、肋高等设计参数对UH…查看全部>>
Ultra-high performance concrete(UHPC)waffle panels have the advantages of light weight,high stiffness and load-bearing capacity,and have good application prospects in projects such as large-span bridge decks and building roofs.Four UHPC waffle panels model with a 1∶2 scale were designed and completed for static loading tests,with a focus on exploring the crack resistance,stiffness,load-bearing capacity,and mechanical characters of the UHPC waffle panels unde…查看全部>>
