Seismic Response of Buildings with Soft Story
Journal of Civil Engineering Inter Disciplinaries, 2020Extending 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.

Seismic Retrofitting Strategies for Soft-Ground-Storied Building
Journal of The Institution of Engineers (India): Series A, 2020During 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 ...

Soft/Weak Story Problems and Solutions for Residential Structures
Improving the Seismic Performance of Existing Buildings and Other Structures, 2009Wood-framed residential structures with soft, weak, or open-front walls are common in areas of high seismicity like the west coast of the United States. Parking below the residential portions of the building, or “tuck-under” parking, is particularly problematic in many buildings built in the 1960s through the 1980s, when stucco and gypsum board were ...

Soft journalism, politics and environmental risk: An Australian story
Journalism, 2011Complex environmental science issues are regularly reported by the news media in highly personalized and symbolic terms in order to make the consequences of environmental degradation and risk comprehensible to the public. This article presents a case study showing how the tension between political statements, human-interest narratives and scientific ...

Soft stories?an appropriate choice for failure theory
The Structural Design of Tall Buildings, 2000A critical review of the of the present approach to the soft story effect during major earthquakes leads to the conclusion that any method based on the usual first theory of failure (assuming that the failure occurs due to high normal stresses) is not adequate and can not predict the failure of soft stories.

Los Angeles Soft Story Retrofit Benefits and Costs
2023California has several seismically dangerous building types, but soft-story woodframe buildings are so numerous and vulnerable that San Francisco, Los Angeles, Oakland, and other cities have taken the unusual step of requiring that they be strengthened to better resist earthquakes 1,2,3,4.

Strengthening of reinforced concrete buildings with soft story irregularity
Materials Testing, 2019Abstract Turkey is one of the most earthquake-prone countries in the world. The studies on the damaged buildings with reinforced concrete structural systems, especially done after the 1999 Gölcük earthquake and other earthquakes in the past, showed that the negative effects of the structural irregularities in the buildings come to light ...

Mitigating San Francisco's Soft-Story Building Problem
Improving the Seismic Performance of Existing Buildings and Other Structures, 2009San 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.

Informing a Retrofit Ordinance: A Soft-Story Case Study
Structures Congress 2012, 2012The San Francisco Community Action Plan for Seismic Safety (CAPSS), among other tasks, addressed the threat that regional earthquakes pose to 4,400 older, soft-story, highoccupancy woodframe residential buildings, like the apartment buildings that collapsed in the 1989 Loma Prieta earthquake.
