Seismic Response of Buildings with Soft Story

Journal of Civil Engineering Inter Disciplinaries, 2020
Extending lifts` reinforced concrete cores to foundations usually restricts services and lobby functions of a building. A core supported on columns at core`s corners is considered a good alternative for sorting out this problem. However, this will cause an abrupt reduction in the lateral stiffness of the building below the cores level i.e.

Hybrid braced frame with buckling-restrained and strong braces to mitigate soft story

Journal of constructional steel research, 2021
The steel concentric braced frames (CBFs) are the common structural system for buildings. Unlike high strength and stiffness, brace buckling in CBFs results in high nonlinear behavior, which causes damage concentration in one or a few stories during a ...

Classification of Soft-Story Buildings Using Deep Learning with Density Features Extracted from 3D Point Clouds

Journal of computing in civil engineering, 2021
Soft-story buildings are seismically vulnerable during earthquakes. The identification of such buildings is vital in seismic risk mitigation to assess the seismic resilience of a given urba...

Intensity and damage statistics of the September 19, 2017 Mexico earthquake: Influence of soft story and corner asymmetry on the damage reported during the earthquake

, 2021
A destructive intraslab earthquake occurred in Mexico City on September 19, 2017 (Mw 7.1), causing significant damage and hundreds of human losses not only in the epicentral area, but also in the States of Morelos, Puebla, Mexico and in Mexico City. Only

Sociotechnical Evaluation of the Soft Story Problem in Reinforced Concrete Frame Buildings in Nepal

Journal of performance of constructed facilities, 2021
In urban and semiurban areas of Nepal, it is a common practice that the construction of reinforced-concrete (RC) framed buildings with infill masonry have open ground floor as commercial sh...

Mitigating San Francisco's Soft-Story Building Problem

Improving the Seismic Performance of Existing Buildings and Other Structures, 2009
San Francisco is in the process of doing something revolutionary: the City is heeding the warning of the moderate damage caused by the Loma Prieta earthquake, and may mandate strong rehabilitation measures for soft-story buildings to prevent catastrophe in future quakes.

Seismic Retrofitting Strategies for Soft-Ground-Storied Building

Journal of The Institution of Engineers (India): Series A, 2020
During seismic events, high-rise buildings with soft ground storey are vulnerable to damage as there is a sudden change of stiffness along its height. In this study, different types of energy dissipation devices, which include lower toggle bracing, double-bracing fluid viscous damper, single-bracing fluid viscous damper and single-bracing friction ...

Building damages during the September 19, 2017 earthquake in Mexico City and seismic retrofitting of existing first soft-story buildings

, 2020
A strong earthquake (Mw = 7.1) hit Mexico City at 13:14 local time on September 19, 2017. The earthquake severely damaged more than 600 buildings and more than 1000 buildings were classified in different risk levels.
