Malawi is an earthquake-prone country that lies within the East African Rift. A large proportion of its population lives in non-engineered single-storey constructions made clay bricks and low-strength mortar. Walls are typically single-skin often lack adequate wall-to-wall connections, leaving them vulnerable to seismic actions. This work reports a comprehensive study on fragility unreinforced ...

This report documents Tasks 4.1 and 4.5 of the CUREE-Caltech Woodframe Project. It presents a theoretical and empirical methodology for creating probabilistic relationships between seismic shaking severity and physical damage and loss for buildings in general, and for woodframe buildings in particular. The methodology, called assembly-based vulnerability (ABV), is illustrated for 19 specific wo...

This study aims to evaluate five different methodologies reported in the literature for developing fragility curves assess seismic performance of RC structures subjected structural pounding. In this context, displacement-based and curvature-based are developed. The use probabilistic demand models (PSDMs) on assessment pounding risk is further estimated. Linear bilinear PSDMs developed, while va...

SSI and site amplification effects are investigated as influences on the seismic fragility of existing reinforced concrete moment-resisting frame dual frame-wall system buildings supported shallow foundations without interconnecting beams. We build upon a holistic methodology that accounts for soil–foundation–structure interaction using modular approach. calculate curves based nonlinear dynamic...

The functionality of elevated water tanks is pivotal to assure after an earthquake as supply expected be uninterrupted. Although with deformed bars are widely studied, limited works exist for smooth bars, although such comprise a considerable fraction, even in the high seismic regions. To quantify vulnerability aging we created analytical fragility functions full, half, and empty reservoir cond...
