Can buckling-restrained brace be used in earthquake-resistant design?

Explore some innovative applications of BRBs in earthquake-resistant design of buildings. As an earthquake-resistant structural element, buckling-restrained brace (BRB) not only adds strength and stiffness but provides excellent energy absorption capability to a structure.

Can a BRB withstand a small earthquake?

The core brace of a BRB is designed to yield under large earthquakes, but remain elastic for small earthquakes. Since energy dissipation is not effected until yielding occurs in the core brace, the use of viscous dampers (VD) to dissipate energy under small earthquake excitations may be beneficial.

What makes a building earthquake resistant?

Earthquake resistant design of buildings depends upon providing the building with strength, stiffness and inelastic deformation capacity which are great enough to withstand a given level of earthquake-generated force.

What is earthquake proof architecture?

Contemporary earthquake proof architecture relies on high tensile cross bracing as well as isolated foundations to meet international standards. Earthquakes are experienced in many parts of the world, but China has some of the worst. In a list of the world’s 10 deadliest earthquakes. China takes out the top two positions.

Did ancient China build earthquake proof buildings?

In fact, they did 2,500 years ago. Ancient Chinese timber building systems have a bracket system called dougong that survives modern day shake [] Developing earthquake proof building technology occupies a lot of time for architects and engineers.

Can a core brace be modeled in a severe earthquake?

However, when subjected to moderate to severe earthquakes, the core brace is expected to undergo significant inelastic deformation, and so the BRBs need to be modeled using elastic–plastic elements with the appropriate hysteretic characteristics.
