摘要
重点研究在条形荷载作用下承压面积比及偏心距等因素对高强混凝土试件局部承压受力性能的影响。根据楔形体模型及极限平衡原理推导出理论计算公式并建立了实用的计算公式,计算结果与实验符合良好。对于偏心受压,依据试验结果确定了偏心距与局压强度提高系数β之间的线性关系以及Ad的取值方法。
The paper is focused on the study of the influence of the factors such as the bearing area ratio and its eccentricity act on the local bearing strength of the high strength concrete. Theoretical formulae are derived from using the cuneafe model and principle of limit equilibrium, and consequently, the equations for practical computation are established. For the case of eccetric loading, a linear relationship between the eccentricity e i and the local bearing strength factor β as well as the simplified method calculating A d are determined.
