Abstract: -The poor seismic performance of the built environment during earthquakes highlights the necessity to design an infrastructure that are both strong and resilient. In this scenario, the architects need to play a critical role in every stages of a building project from conceiving to commissioning including the site selection, preparation of conceptual layouts, structural design, seismic detailing, construction and engineering of non-structural elements. A basic understanding of architectural aspects that govern the seismic behaviour of buildings is essential to ensure an earthquake resistant construction.The paper presents various aspects to be critically reviewed by architects in the preparation of earthquake resistant conceptual layouts. The configuration issues affecting the earthquake performance and their solutions are discussed. Finally, the importance in engineering and detailing of non-structural elements is highlighted.
Keywords:- Earthquake, Conceptual layout, Seismic structural system, Shear wall, Soft storey, Non-structural elements.
I. INTRODUCTION
A large part of India is prone to strong earthquakes with a huge risk of human lives and property. The 2001 Bhuj earthquake was an eye opener with significant damages to many modern multi-storey reinforced concrete frame buildings. The earthquake has resulted in a total tangible economic loss of Rs. 30,000 crores which is almost five times annual budget for Gujarat state[1]. Poor architectural configuration, inadequate structural design, improper detailing and poor construction practices were found to be the major concerns.Architects being important stakeholders of built environment, have a critical and responsible role in ensuring earthquake resistant construction. They occupy a key position in project conceptualization, planning and implementation. Poor conceptual design and detailing of various elements by the architect will seriously impair the ability of structural and construction engineers to incorporate earthquake resistance in buildings.
