Project for Technical Development to Upgrade Structural Integrity of Buildings in Densely Populated Urban Areas and
its Strategic Implementation towards Resilient Cities
Technologies for enhancing structural resilience of buildings in Dhaka and their effective implementation schemes are
proposed.
The proposed macro-modeling approach could capture the seismic behavior of RC frame with masonry infill wall.
