, a model for calculatingallowable tensile strainfor full-graded concrete is proposed. 在考虑动荷载效应、微裂隙影响、骨料粒径效应等因素对混凝土极限拉应变影响的条件下,提出了全级配混凝土容许拉应变计算公式。 6) stress allowed 允许应力 补充资料:允许暴露极限 ...
In this paper,the permissible tensional prestress of the RC beams strengthened with prestressed CFRP is discussed in terms of the tensile strength of concrete,the shear strength of interface between concrete and CFRP,and the tensile strength of CFRP. 文中从混凝土抗拉强度、混凝土和CFRP层界面抗剪强...
Ban SengChoo, inAdvanced Concrete Technology, 2003 25.2.2Permissible stress method In thepermissible stressmethod, the ultimate strengths of the material were divided by a safety factor to provide permissible design stresses which were considered to be within the elastic range. An elastic method of...
in three areas including effective prestress,interfacial stress and mode of failure.The high level of prestress will cause crack on the tensile concrete and high shear stresses on interface between concrete and CFL.In order to avoid the failure mode of CFL brittle failure,the permissible prestressed...
