摘　　要：为摸清芮城县房屋的抗震性能,开展房屋建筑抽样详查工作。分别从房屋建筑类别、数量占比和分布情况等方面展开调查,并对砖混结构房屋的抗震性能进行评估。主要对有震害统计的无圈梁、有圈梁构造柱砖混砌体结构房屋的窗间墙宽与窗上带高、窗上带跨高比和窗间墙高宽比、窗间墙与窗上带刚度比的相互关系进行研究。同时基于地震中窗上带优先出现损伤,可最大程度保护房屋抗震柱或承重墙,保持建筑物大震不倒的判断规则,对芮城县30栋砖混房屋的抗震性能做出评判。研究结果表明,芮城县城区砖混结构房屋抗震性能为一般-较差,乡镇的为较差-差。In order to assess the seismic performance of houses in Ruicheng County,a sampled detailed inspection of building construction was conducted.The investigation covered aspects such as building types,proportional distribution,and spatial arrangement.The seismic performance of reinforced brick structure houses was evaluated,focusing on the relationship between the width of walls between windows and the height of the lintel above windows,the ratio of lintel height to wall height,the ratio of wall height to wall width,and the stiffness ratio between walls between windows and lintels.Additionally,based on the principle that damage often initiates from lintels during earthquakes,and to maximize the protection of seismic columns or load-bearing walls to maintain the rule that buildings do not collapse during significant earthquakes,an evaluation of the seismic performance of 30 reinforced brick houses in Ruicheng County was conducted.The results indicate that the seismic performance of reinforced brick houses in urban areas of Ruicheng County ranges from moderate to poor,while in rural areas,it ranges from poor to very poor.
