新型UHPC组合肋预应力混凝土叠合板力学性能试验研究
Experimental Study on Mechanical Properties of New UHPC Combined Rib Prestressed Concrete Composite Slabs
文中通过开展静力荷载试验研究,对比分析了钢管桁架预应力混凝土叠合板(简称PK3板)和两种不同新型超高性能混凝土(ultra-high performance concrete, UHPC)组合肋预应力混凝土叠合板(简称TY板)的静力力学性能差异。本试验采用逐级加载方案,对各级加载工况下试件的板底裂缝开展、挠度变形、钢筋桁架应变、板底应变等参数进行系统测试,并对各类预制板在变形过程中的抗裂能力、荷载-挠度变化趋势、钢筋桁架应变分布等力学响应特征开展了系统性对比分析。试验结果表明:相较于PK3板,TY板在相同荷载条件下,不仅裂缝宽度更小,且扩展速率更缓,在裂缝控制性能上展现出显著技术优势;且TY板的挠度也明显小于PK3板的挠度,表明TY板具有良好的抗弯能力;对于不同类型的TY板,发现梯形桁架型的TY板相比于普通钢筋桁架型TY板表现出更优的力学性能。本试验通过对TY板裂缝控制性能与刚度特性的系统验证,证实其为一种性能优良、适用场景广泛的预制装配式叠合板板材。
In this paper, static load tests were carried out to comparatively study the differences in the static mechanical properties of a prestressed concrete composite slab with steel-tube truss (PK3 slab) and two different ultra high-performance concrete (UHPC) new combined rib prestressed concrete composite slabs (TY slab). The test was conducted by loading step by step to observe the crack development, deflection deformation, reinforcement truss strain, and strain of the slab bottom under loading conditions at all levels. A systematic comparative analysis was carried out on the crack resistance, load-deflection trends, and reinforcement truss strain conditions of the various prefabricated slabs during the deformation process. The test results show that compared with the PK3 slab, the TY slab has a smaller crack width and slower crack propagation rate under the same load, which shows obvious advantages in crack control. The deflection of the TY slab is also obviously smaller than that of the PK3 slab, which shows good bending capacity. For different types of TY slab, it is found that the trapezoidal truss-type TY slab shows better mechanical properties compared with ordinary steel truss-type TY slab. Through the verification of crack control and stiffness of the TY slab in this experimental study, it is an excellent and ideal prefabricated assembled composite slab.
