Seismic Deformability of Existing RC Buildings in Dhaka Bangladesh, Through the Basic Experiment
Abstract eng: Present Bangladesh National Building Code (BNBC 1993) became mandatory in 2006, and many existing RC buildings in Dhaka, the capital of Bangladesh, are not in compliance with the seismic requirements of the Code. Because of the low strength of concrete and small section sizes of a column, the numerical value of axial force ratio (η=N/b·D·F c , N = axial force, b·D= width and depth, Fc= compressive strength of concrete) is high. The shear reinforcement of a column is not enough. These conditions reduce the seismic deformability (ductility). An infilled brick wall in a RC frame is commonly used, which is a non-structural element, but it affects the behavior of a frame. An experimental approach was taken to get indicative information of the seismic deformability of existing RC buildings for the seismic assessment and retrofit. The results indicate,
