高性能混凝土梁受力性能试验研究

Experimental Research on the Stress Behavior of High Performance Concrete Beams

通过6根模型梁的三分点加载试验,对高性能混凝土梁的正截面受力性能进行了试验研究,研究了掺加高效减水剂,粉煤灰、磨细矿渣的高性能混凝土梁的正截面受力性能,并将试验结果与有关混凝土结构设计规范的计算值对比分析,验证了混凝土结构设计规范(GB50010-2002)、高强混凝土设计与施工规程(CECS104:99)对高性能混凝土梁的正截面设计计算的适用性,为大掺量外掺料高性能混凝土在工程上的应用提供了试验依据。

This paper expounds an experimental study on the stress behavior of high performance concretebeams with tests of 6 specimens and makes a detailed analysis and comparison of the stress behaviors of highperformance concrete beams respectively mixed with superplasticizer, fly ash and blast furnace slag. A comparison is also made between the test results and the theoretical calculation. The comparison proves the applicability of the design norm for concrete structures [GBS0010 - 2002] and the technical specification for highstrength concrete structures [CECS104：99] to the design and calculation of the stress capacity of high performance concrete beams, thus providing a basic test support for the employment of high performance concretewith large quantity of mineral admixtures.
