Study on empirical seismic codal guidelines for masonry buildings in Kollam, Kerala, India

Masonry structures fail miserably due to lateral loads. Recent earthquakes in India and the world and the resulting losses highlighted the structural inadequacy of masonry buildings to seismic loads. Increase in frequency of earthquake in Kerala recently and increasing concern motivated the study. L...

Recent earthquakes in India and the world and the resulting losses highlighted the structural inadequacy of masonry buildings to seismic loads.
