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.

What is the philosophy of earthquake resistant design?

Developing a sufficient level of familiarity with this rationale, sometimes called the “philosophy of earthquake resistant design”, is essential before embarking on conceptual design for earthquake resistance followed by the required structural analysis and detailing calculations prescribed by seismic codes of practice.

Does a design earthquake protect against structural damage?

Such a design achieves only “partial” protection against structural damage for the design seismic hazard and may incur considerable repair costs and downtime, while the probability for an enforced demolition in the aftermath of a seismic event exceeding the nominal design earthquake is likely.

Do steel braces protect against earthquakes?

The use of damping devices has gained popularity because they have been proven to be effective against severe structural damage from large earthquakes. Steel braces are often used for seismic design and retrofit of steel frame structures. Steel braced frames have been shown to exhibit good seismic performance under strong earthquakes.

Do ductile structures resist a design earthquake?

On the antipode, in the case of a structure designed to resist the design seismic action through linear behaviour on a strength-based design (full protection against structural damage for the design earthquake), no special measures for ductile behaviour are needed to resist the design earthquake.

Can earthquakes bolster the resilience of building structures?

Earthquakes, one of humanity's major natural challenges, are notoriously unpredictable and sudden, making accurate forecasting a formidable task. In response, researchers have devised a range of techniques to bolster the seismic resilience of building structures, achieving commendable progress in recent years.
