Abstract

Earthquake-resistant design is one of the greatest challenges that must be considered by the Architect because it is a serious natural disaster that affects the stability and durability of the building. Due to the connection between the seismic behavior of buildings with its formal configuration and the differences in seismic resistance between regular and irregular buildings, the research problem presented as the confusion of seismic behavior of irregular buildings and their difference from the regular buildings when earthquakes occur. The aim of the research is to clarify the differences between regular and irregular configurations, also clarifying the design considerations in earthquake-resistant design for regular and irregular buildings by constructing a cognitive framework that clarifies the concept of configuration and the differences between regular and irregular configuration, and design considerations that must be conformed to in designing earthquake-resistant buildings to determine the main and secondary vocabulary of the theoretical framework. The research uses an inductive methodology (descriptive and analytical) through the selection and analysis of two different case studies. The major result shows that the formal configuration is considered one of the most important factors that determine the seismic behavior of buildings, and due to its connection to the structural system, earthquake-resistant design requires a set of interacted decisions between architectural and structural engineers to achieve the best configuration of the building in resisting earthquakes. The regular configuration of buildings provides the possibility to predict the seismic behavior of the building, while irregular configuration of buildings exhibits unexpected seismic behavior, requiring special construction solutions that are mostly cost-effective.
