Abstract

Saudi Arabia’s kingdom is not free from seismic tremors. It has encountered numerous quakes amid the ongoing history, and the past investigations on this field exhibited this contention. Many existing structures in Abha City have not been intended to oppose seismic forces. Moreover, it is imperative to contemplate the reaction of these structures under seismic conditions. Likewise, there is a lack in the examinations done in this field identified with Abha City. Consequently, existing structures ought to be assessed with respect to their ability for opposing expected seismic impacts before recovery works. Investigation was completed by utilizing auxiliary examination program (SAP2000) [1] with the utilization of static technique proposed by the Saudi Building Code (SBC) [2] to decide the reaction of regular multi-storey structures made of strengthened cement because of quake ground loads. Objective of this paper is to assess the execution of existing multi-storey RC working in Abha City under seismic loads. To accomplish this goal, a 3D model for eight-storey RC building was developed utilizing SAP2000 examination program, though tremor loads were determined by static technique. Outcomes got from this paper inferred that the present plan of existing structures in Abha city is dangerous for the present seismicity of Abha territory. At last, it has been verified that RC shear walls signified a truly reasonable procedure, as a fortifying method for existing RC structures, to lessen the seismic defenselessness of these structures.
沙特阿拉伯阿卜哈市一座八层既有钢筋混凝土建筑的评价与加固
沙特阿拉伯王国并非没有地震。在不断发展的历史中,它遇到了无数的地震,过去对这一领域的调查显示了这一论点。阿卜哈市的许多现有结构并没有打算抵抗地震力量。此外,必须考虑这些结构在地震条件下的反应。同样,在阿卜哈市进行的这一领域的检查也缺乏。因此,在恢复工程之前,应评估现有结构抵御预期地震影响的能力。利用沙特建筑规范(SBC)[2]提出的静力学技术,利用辅助检测程序(SAP2000)[1]完成了对钢筋水泥规则多层结构在地震荷载作用下的反力测定。本文的目的是评估在地震荷载作用下,阿卜哈市现有多层钢筋混凝土工程的执行情况。为了实现这一目标,利用SAP2000检测程序开发了八层钢筋混凝土建筑的三维模型,尽管地震荷载是通过静力技术确定的。本文的研究结果表明,目前阿卜哈市既有结构的规划对阿卜哈地区目前的地震活动性是危险的。最后验证了钢筋混凝土剪力墙作为现有钢筋混凝土结构的加固方法,是一种真正合理的方法,可以减轻现有钢筋混凝土结构的抗震设防能力。
