A simplified flexural expression for stiffness B_d of R. C. flexural members with crackings under short-term loading, is presented in this paper, It is derived by means of regression analysis from the deflection measurements of 190 members including T, inverted T, and Ⅰ sections. The results are compared with those obtained by the formulas given in the current Reinforced Concrete Structural Design Code(TJ10-74), showing that the average f~s/f is close to and value c, slightly larger than the latter.The new expression...

A simplified flexural expression for stiffness B_d of R. C. flexural members with crackings under short-term loading, is presented in this paper, It is derived by means of regression analysis from the deflection measurements of 190 members including T, inverted T, and Ⅰ sections. The results are compared with those obtained by the formulas given in the current Reinforced Concrete Structural Design Code(TJ10-74), showing that the average f~s/f is close to and value c, slightly larger than the latter.The new expression is rather simple in computation and also provides clear quantitative relation for the main factors affecting the stiffness, so it is of better practical significance.

Based on the data from a scries of comparative tests, this paper deals with the influence of size and shape factors of samples on the results of point load tests of rocks statistically. In order to find out the relationship between point load test results and all the influencing factors so as to establish a more reasonable expression, the progressive regression analysis was undertaken by using a microcomputer. On this basis, a new expression of point load strength accounting for all the main influencing factors is suggested as PLS=P/A_f Where PLS is the point load strength (in MPa or Kgf/cm~2), Pis the load required to break the specimen tested (in N or Kgf), A_f is the area of the surface of fracture (in cm~2) . It can be seen that the now expression has a definite physical meaning. By using it, the necessity of making size correction and limiting the size and shape of samples will be eliminated and simplification of the test and data proressing will be made possible.

本文在大量对比试验的基础上,通过对试验数据的统计分析,论证了试样的尺寸及形状等因素对岩石点荷载试验结果的影响。为了找出点荷载试验结果与所有影响因素之间的关系,分清这些影响因素的主次和重要程度,以便建立更合理的点荷载强度计算公式,作者运用数理统计方法并通过微机的计算分析,找出了对点荷载试验结果有重要影响的和不可忽略的因素,并据此提出了包含上述因素在内的新的点荷载强度计算公式为:PLS=P/A_f式中PLS为点荷载强度(MPa或Kgf/cm~2),P为破坏荷载(N或Kgf),A_f为破坏面面积(cm~2).点荷载强度(PLS)定义为在点荷载作用下试样破坏面单位面积上所能承受的最大荷载.利用这个公式,可以不必限制试样的尺寸和形状,不必进行尺寸修正,使测试及资料整理工作大大简化,更利于点荷载试验技术的推广应用.新的公式由数理统计方法分析而得,物理概念明确,特提出来供商榷.
