Experimental study on in-plane mechanical behavior of half steel ultra-high performance concrete composite panel element
摘要
Abstract
To study the in-plane mechanical behavior of the half steel ultra-high performance concrete composite plate(HSUHPC),twelve HSUHPC panels are designed and tested by a self-developed planar bi-directional multi-functional element tester in this paper.The test program includes three uniaxial tensile tests,three biaxial tensile tests,and six cyclic shear tests.The results show that the steel plates,bars,and UHPC can realize compatibility of deformation at the elastic and initial cracking stages and they can sustain the load together at all loading stages.Effective stress redistribution can be developed between the steel bars and UHPC.Due to the high residual tensile strength and significant strain hardening properties,the UHPC is capable of providing at least 50％of tensile and shear capacity.The reinforcement ratio and steel ratio both have an influence on the bearing capacity of the HSUHPC plate.The biaxial tensile condition has little influence on the bearing capacity of the HSUHPC plate,of which the capacity is close to that of the HSUHPC plate under uniaxial tensile condition.Based on the test data and methods in the codes,formulas for calculating the tensile and shear capacities are proposed for the HSUHPC element.The deviation between the calculation results of the formula and the test results is within 10％,which proves that the high accuracy of the proposed formula.关键词
