Steel Bracing of RC Frames for Seismic Retrofitting
https://ascelibrary.org/doi/abs/10.1061/(ASCE)0733-9445(1990)116:1(55)
Abstract. The use of steel bracing systems for retrofitting seismically inadequate reinforced concrete frames is examined. Diagonal bracing provides an excellent approach for strengthening and stiffening existing buildings for lateral forces. A variety of retrofitting objectives, ranging from drift control to collapse prevention, can be achieved. The designer can determine the force …

The reduction in the displacement along X direction is about 68.98% by use of steel tube section and 65.95% by the use of steel angle section. The performance of steel tube section braced frame is better than steel angle section frame. Thus, by retrofitting the RCC structures with steel braces, the effect of lateral loads can be reduced.

The promising behavior of internal bracing system that utilizes diagonal braces directly connected to the RC frame (Maheri and Sahebi 1997; Mahrenholtz et al. 2014), which has also eliminated the need for the intermediary steel frame, have prompted the use of direct internal steel braces for seismic rehabilitation of RC frame structures using concentric braces (Abou …

The use of steel bracing systems for strengthening or retrofitting seismically inadequate reinforced concrete frames is a viable solution for enhancing earthquake resistance. Bracing system reduces bending moments and shear forces in the columns. The lateral load is transferred to the foundation through axial action.

This paper focuses on optimal design for dissipative steel bracing in seismic retrofitting of gravity load designed RC frame buildings. An optimized iterative force/strength-based design procedure is presented, for simultaneous yielding of bracing of all storeys, in order to induce an global damage mechanism in the building which maximizes the hysteretic …

Seismic retrofit of RC frames with steel bracings was first introduced by Sugano . Several analytical and conceptual studies regarding bracing was done by Baduox et al. [ 17 ] . In their study, frames with short and weak column were studied, and it was found that bracing can be used to specifically target the strength and stiffness deficiencies, but inelastic buckling of …
