What is a fixed adjustable photovoltaic support structure?

In order to respond to the national goal of “carbon neutralization” and make more rational and effective use of photovoltaic resources, combined with the actual photovoltaic substation project, a fixed adjustable photovoltaic support structure design is designed.

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 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.

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.

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.

Can steel braces be used for seismic design & retrofit?

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. However, as shown in Fig. 1, steel braces are prone to buckling under strong dynamic loads caused by earthquake and wind.
