基于“2.06台湾地震”对混凝土梁柱构造检测鉴定的探讨

Investigation on Inspection and Appraisal for the Details of RC Beam and Column Based on the “2.06 Taiwan Earthquake”

基于"2.06台湾地震"震后建筑倒塌检测结果,结合GB 50292-2015《民用建筑可靠性鉴定标准》的相关要求及相应的结构检测鉴定经验,针对钢筋搭接长度、箍筋间距、箍筋加密区长度、钢筋搭接错开百分率及钢筋弯钩长度和角度的检测方法及其安全性等级评定准则提供了部分建议,同时建议在目前检测技术下,钢筋搭接长度、箍筋间距、箍筋加密区长度及钢筋搭接错开百分率应作为必检项目。

Combined with the requirements in GB 50292-2015“Standard for Appraisal of Reliability of Civil Buildings”and the experience for inspection,the method and the criterion for appraisal for lapped length of steel bar,stirrup spacing in critical region,length of critical region,the joint dislocation percentage,length and angle of the crooked hook were proposed based on the“2.06 Taiwan Earthquake”,at the same time,it is also proposed that the lapped length of steel bar,stirrup spacing in critical region,length of critical region and the joint dislocation percentage must be tested under the recent condition of technology in this paper.
