Braced Structural Frames Most of high rise Building Has Braced Structural Frames and even though they are often isolated within buildings and don‟t include the majority of the steel member and design and construction teams pay a lot of attention to them because they are unique and serve a critical function. Basically, bracing systems are widely used at construction sites to reinforce building structures in which diagonal supports intersect. Braced Structural Frames provides one or more of the following functions: Control buckling of the main beams Load distribution Dimensional control
Vertical loads in Braced Structural Frames- Bracing between lines of columns provides load paths to transfer horizontal forces to ground level and provide a stiff resistance against overall sway. Horizontal loads in Braced Structural Frames- At every floor level, bracing in a horizontal surface, generally provided by floor plate actions,also provides a load path to transfer the horizontal forces to the surface of vertical bracing. In general, a braced frame consists of diagonal members used to resist lateral loads. A braced frame may come in lots of varieties. Some examples of braced frames are as below. Concentrically Braced Frames Concentrically Braced Frames are strong, stiff and ductile, making them ideal for seismic framing systems. The inelastic behavior of the brace provides most of the ductility, but in order to fully utilized the frames, the connections and framing members must also be taken into account. Therefore, it is important to consider not only the performance of the brace when designing consideration, but also the ability for the connections and the framing members to withstand the strength and deformation demands transferred from the brace during cyclic loading. Through these considerations, a maximum amount of energy can be dispersed before the system fails.
