页岩模数多孔砖局部受压性能的研究

【摘要】 GBJ50003—2001《砌体结构设计规范》的砌体局部受压强度提高系数γ的取值,是根据实心粘土砖的试验结果统计回归而得。随着墙体材料的改革,越来越多的新型砌块砌体应用到建筑中,我们应该看到规范中的γ值难以包容各种新型的砌块砌体。为此我们对页岩模数多孔砖砌体的局部受压进行了试验研究,并对适用页岩模数多孔砖的局部受压强度提高系数γ及其计算公式中b值的确定进行了研究。为页岩模数多孔砖在实际工程中应用提出建议。更多还原

【Abstract】 In GBJ 5003-2001"Masonry Wall Structure Design Code",partial compression strength gain factor of masonry wall γ is obtained by statistical regression based on the result of tests of solid clay bricks.With the reform of wall materials, more and more new blocks and masonry walls are used in the building.We should notice that γ value in the Code is difficult to include various new blocks and masonry walls.Therefore,we have made partial compression tests on shale modulus porous brick wall and studied on factor of gain in partial compression strength γ suitable for shale modulus porous brick and on determination of b value in calculation formula.Suggestions are made for application of shale modulus porous brick to practical engineering.更多还原
