Abstract

The Service life of a building is the period from commencement of service to the time just before costly maintenance becomes necessary for continued meeting of minimum performance requirements. Knowledge of service life determines whether to demolish and replace a building or major repairs are required and the absence of information on this has led to many building failures. This research therefore aimed to determine the Reference Service Life (RSL); a parameter required for the evaluation of a building’s Service Life. Twenty reinforced concrete multistorey residential buildings around the Federal University of Technology Akure (Nigeria) were assessed via visual inspection, material testing, and structural analysis. Information obtained from the assessment was used to develop a comprehensive open-ended service life database. Non-destructive tests were conducted on the buildings’ structural elements and the results used to determine the service life of each of the buildings with the aid of Life 365 Software. Weighted factors which depend on the quality characteristics, operational conditions and the environment of the buildings were used as a grading system for the assignment of sub-factors for the adjustment of the Life 365 service life values, leading to a value of 29 years as the Reference Service Life (RSL) for the study area. The result obtained will benefit construction professionals and appropriate regulatory authorities in the study area while the procedure can be adopted for service life assessment in other locations lacking appropriate database.
钢筋混凝土多层住宅参考使用寿命的确定——以尼日利亚阿库雷为例
建筑物的使用寿命是指从开始使用到持续满足最低性能要求所需的昂贵维护之前的一段时间。使用寿命的知识决定了是拆除和更换建筑物还是需要大修,而缺乏这方面的信息导致了许多建筑物的故障。因此,本研究旨在确定参考使用寿命(RSL);评估建筑物使用寿命所需的参数。通过目视检查、材料测试和结构分析,对尼日利亚阿库尔联邦理工大学周围的20栋钢筋混凝土多层住宅楼进行了评估。从评估中获得的信息被用于开发一个全面的开放式使用寿命数据库。在life 365软件的帮助下,对建筑物的结构元件进行了无损检测,结果用于确定每栋建筑物的使用寿命。将取决于建筑质量特征、运行条件和环境的加权因子用作分配子因子的分级系统,以调整寿命365使用寿命值,从而得出29年的值作为研究区域的参考使用寿命(RSL)。所获得的结果将有利于研究区域的建筑专业人员和适当的监管机构,而该程序可用于缺乏适当数据库的其他地区的使用寿命评估。
