The structural system consists of RC frames in the first three levels and the fourth level has structural steel frames. In addition, the building has rigid diaphragm and regular plant. First, a static linear analysis was performed to design all structural elements. Then, a static pointer analysis was performed to obtain real and idealized capacity curves and performance points in all frames. In the obtained results showed greater ductility in frames of direction X and greater reserve of resistance in the external frames whereas the determined points of realization showed values of resistance suitable for all the frames, but low stiffness in two directions X marks. The seismic action is carried out through various accelerograms compatible with the synthetic design spectrum defined by the seismic codes used in this chapter with three intensity levels corresponding to three specific limit states. Dynamic analysis is used to calculate ductility, resistance, and maximum displacement parameters. It was obtained that an X-direction framework reached the collapse of the State Limit in a very rare earthquake, which implies a general collapse of the building. Finally, an incremental dynamic analysis was performed to obtain fragility curves and damage probability matrix; it was evidenced that the structure has a very high probability of significant lateral displacement despite a suitable and normative design of the structural elements.
Framed in the construction is the assembly of pieces to give a structure support and shape. The framing materials are generally wood, engineered wood, or structural steel. The alternative to framed construction is generally referred to as dome wall construction which is made up of horizontal layers of stacked materials such as building logs, masonry, rammed earth, adobe, etc.
The construction frame is divided into two broad categories: heavy frame construction (heavy frame) if the vertical supports are few and heavy, such as in framing, framing, post framing or steel framing or many and more small called light frame) including balloon, platform and light steel frame. Construction of light frame with standardized dimensional wood has become the dominant building method in North America and Australia because of its economy. The use of minimal structural material allows builders to enclose a large area with minimal cost while attaining a wide variety of architectural styles.
Modern light structure structures often gain strength from rigid panels (plywood and other plywood-like materials such as Oriented Boards (OSB) used to form all or part of wall sections) but until recently carpenters employed various forms of diagonal reinforcement to stabilize walls. Diagonal reinforcement remains a vital part of the interior of many roofing systems, and wall braces are required by building codes in many municipalities or by individual state laws in the United States. Special framed walls are becoming more common to help buildings meet the requirements of earthquake engineering and wind engineering.
