Earthquake-resistant design philosophy requires three distinct structural performance objectives of ensuring no damage, minor repairable structural damage and no collapse to be met corresponding to three levels of earthquake shaking, namely minor, moderate and severe. Most studies in the field of earthquake resistant design over the last several decades have been focused towards the development of analysis, design and detailing of moment-resisting frame buildings. In this regard, moment-resisting frame has become the structural system of choice in most low- to mid-rise reinforced concrete (RC) buildings. But in regions of high seismicity, the performance of these buildings has not been satisfactory due to various reasons; even storey mechanisms have occurred in many multi-storeyed RC buildings across the world in past earthquakes. In this context, use of RC structural walls to supplement moment frame buildings have emerged as an important alternate to resist strong earthquake shaking. But detailed quantitative guidelines for multi-level earthquake resistant design of RC moment-frame buildings with structural walls are not available. Therefore, this study attempts to propose a graded design requirement of RC buildings with structural walls to ensure their earthquake behaviour to be consistent with the design philosophy. In particular, two important design parameters are investigated, namely the structural wall plan density and the corresponding column-to-beam flexural strength ratios. In this first seminar, some key aspects of current earthquake resistant design practice and behaviour of RC moment frame buildings designed for various levels of earthquake shaking are presented. The findings illustrate the inadequacy of moment frames in regions of high seismicity and reinforce the ultimate objective of this study.
