if you live in one of the 16 states with the highest earthquake risk , it’s important to protect your investment and earthquake-proof your home. Houses built before 2000 don’t usually meet current seismic building standards. Unless you own a newly-constructed property, it’s a good idea to get your home retrofitted before an earthquake has a chance to strike. over the past few decades, there have been a number of devastating earthquakes across the world that have caused major structural damage to cities, homes, and individuals. Organizations such as earthquake country alliance have emerged in an effort to help protect people and property from earthquake damage.

Written by saunders construction on 25th may 2023 a soft-story retrofit refers to a building that is a multi-story structure built with a first floor that is open in nature, much less rigid than the floors above. For example, multi-family apartment buildings with tuck-under parking or subterranean parking and retail centers with a large store front on the first floor are typical soft-story buildings that need seismic retrofits. A seismic retrofit is a process of modifying existing buildings and structures to improve their ability to withstand seismic activity, such as earthquakes. The retrofitting process may involve strengthening the foundation, walls, roof, and other structural components of the building to make them more resistant to seismic forces.
No two buildings are exactly alike. In fact, some that may seem at first appearance to be identical can display significant differences based on a number of factors, including structural composition, materials, the wear and tear on the building, even the composition of the soil beneath it. It’s impossible, then, to give specifications to a retrofit project without first doing a comprehensive engineering study that examines not only as-builts, but inspects the property itself. That said, here are some basic approaches to retrofitting applied to various types of structures found to be vulnerable to damage or collapse in a major earthquake.
Analysis of steel frames with bracings for seismic loads 2019 • iaeme publication in recent decants steel structure had played an important role in construction industry. Providing strength, stability, ductility for buildings designed for seismic loads. It is necessary to design a structure that can withstand under seismic loads. Providing steel knee braces is one of the structural systems used to resist earthquake forces on structures. Steel bracing is economical, easy to erect and occupies less space which is flexible to design to meet the required strength and stiffness. There are various types of steel bracing (x, knee bracing). In knee brace frame system (kbfs) the non-buckling diagonal bracing provide most of the lateral stiffness, the flexural yielding of knee element.
