Abstract

A moderate earthquake with 6.0-magnitude hit Sabah in 2015 especially in Ranau, Sabah has been labelled as one of the most powerful earthquakes ever in Malaysia. Numerous buildings in Sabah have become defective with the severity level of damages as absolute (non-repairable) in the RC beam-column joints and soft-storey structures. Seismic design and construction requirements were not considered in most buildings in Sabah. Hence, this research is to investigate how to mitigate the effect of earthquake on the low-rise building using a more practical and economical method. A stilt house model is developed using ABAQUS software to determine the behaviour of the stilt, low-rise building subjected to earthquake by constructing shear wall at the short columns support. There are 4 models constructed namely, frame model without shear wall (W1), with shear wall of 100mm (W2), 300mm (W3) and 500mm (W4). The results of seismic response are evaluated and compared. Different length of shear wall affects the displacement and stress of the frame model. As shear wall length increases, the displacement, stress at columns and stress at walls decreases. Thus, adding a shear wall can be used to retrofit stilt houses and a credible way to mitigate damage due to earthquake load for new houses along hill slopes

地震作用下沙巴吊脚楼剪力墙加固

2015年，沙巴发生了6.0级的中等地震，尤其是在拉瑙，沙巴被认为是马来西亚有史以来最强烈的地震之一。沙巴的许多建筑物都有缺陷，在钢筋混凝土梁柱接缝和软层结构中，损坏的严重程度为绝对(不可修复)。沙巴的大多数建筑物都没有考虑抗震设计和施工要求。因此，本文的研究是探讨如何用一种更实用和经济的方法来减轻地震对低层建筑的影响。利用ABAQUS软件建立了高跷房屋模型，通过在短柱支撑处建造剪力墙来确定高跷低层建筑在地震作用下的行为。共构建了4个模型，即无剪力墙框架模型(W1)、剪力墙为100mm (W2)、300mm (W3)和500mm (W4)。对地震反应结果进行了评价和比较。不同的剪力墙长度会影响框架模型的位移和应力。随着剪力墙长度的增加，剪力墙的位移、柱端应力和墙端应力均减小。因此，增加剪力墙可以用来改造高跷房屋，也是减轻地震荷载对山坡上的新房屋造成的破坏的可靠方法

期刊介绍： The International Journal of Integrated Engineering (IJIE) is a single blind peer reviewed journal which publishes 3 times a year since 2009. The journal is dedicated to various issues focusing on 3 different fields which are:- Civil and Environmental Engineering. Original contributions for civil and environmental engineering related practices will be publishing under this category and as the nucleus of the journal contents. The journal publishes a wide range of research and application papers which describe laboratory and numerical investigations or report on full scale projects. Electrical and Electronic Engineering. It stands as a international medium for the publication of original papers concerned with the electrical and electronic engineering. The journal aims to present to the international community important results of work in this field, whether in the form of research, development, application or design. Mechanical, Materials and Manufacturing Engineering. It is a platform for the publication and dissemination of original work which contributes to the understanding of the main disciplines underpinning the mechanical, materials and manufacturing engineering. Original contributions giving insight into engineering practices related to mechanical, materials and manufacturing engineering form the core of the journal contents.
