我们于1977年提出了偏心受力构件刚度和裂缝计算方法。最近恨据国内后来陆续进行的100多根短柱和长柱,以及70根偏心受拉构件的试验资料,对原建议公式中的某些系数略作了调整。这项建议填补了我国钢筋混凝土结构设计计算方法中的一个空白,它和我们早先提出并为规范TJ 10-74采纳的受弯构件刚度和裂缝计算方法组成一个统一的计算体系,可供即将修订的新规范参考。 在本文中,用我们试验的68根偏心受压构件的试验资料进行了验算,表明建议的方法能较好地符合试验结果。
In 1977, we proposed a method for calculating the stiffness and cracks of eccentrically loaded members. Recently, he hated to make some adjustments to some of the coefficients in the original proposed formula based on test data of more than 100 short columns and long columns and 70 eccentric tension members that were successively carried out in China. This proposal fills a gap in the design calculation method for reinforced concrete structures in China. It forms a unified calculation system with the calculation methods for stiffness and cracks of the flexural members that we proposed earlier and used to regulate TJ 10-74. The new specification reference. In this paper, the test data of 68 eccentrically compressed components we tested were used to verify the results, indicating that the proposed method can better meet the test results.
