“…To scale back such impact, infill wall and shear wall were introduced conjointly and discovered that the buildings having additional range of bays will resist the seismic force (Kaltakci and Ozturk 2012). Various bracing system can be used to resist the lateral load by transferring the shear force from joint to the web member provided as the brace and later transferred to the ground through the column (Guerrero, Escobar, and Teran-Gilmore 2018). The distribution of mass and stiffness in each horizontal and vertical plane of the building determines its behavior during an earthquake; each of these factors varies in the case of mountainous buildings with irregularity and imbalance due to step back and step back set back configuration.…”

Earthquake is a natural disaster that occurs when the Earth's crust moves suddenly. Every year, hundreds of earthquakes strike various parts of the globe. According to previous research, buildings that are built on sloped terrain are the most susceptible to earthquakes. This is attributable to the different heights of the columns on the ground floor. By changing the height of the column at the base of a 2-D Conventional RCC Frame and a Special Confined RCC Frame, an experimental investigation was carried out in this study. The parameters like load verses deflection, crack width and stiffness degradation was used to draw comparison between the Conventional RCC Frame and Special confined RCC Frame under Reverse Cyclic Loading by using Push and Pull Jack. Hysteresis curve clearly shows that Special Confining reinforcement provided for the column throughout the span because of columns with varying stiffness provides additional strength and performance against lateral force by dissipating energy. The ductility of Short column improved at initial stage, meanwhile the displacement of the Special confined RCC frame with short column also improved due to ductile reinforcement which leads to reduction in failure rate and arrest the sudden failure of the short columns in the frame as that is physically visible from the crack pattern.

Safety during earthquakes should be a human right and shall be accessible not only to those who can pay for proprietary high-tech devices but to everyone. Based on that, this study has been developed with the intention of helping to improve the seismic safety in the developing world. Within this paper, a low-cost, low-tech seismic energy dissipation device is proposed. Its experimental behavior under seismic loading is assessed. The device type is buckling-restrained brace (BRB) and, according to its characteristics, it is suitable for new and existing, medium- to low-rise structures. First, the device characteristics and fabrication process are presented. Then, its structural response, in terms of the hysteretic behavior, ductility, and dissipated energy – as obtained from experimental tests – is shown. Experimental results show an excellent behavior of the proposed device. As a result, it can be said that the device is reliable and its use is recommended for new, and retrofitting/upgrading existing, structures. Design recommendations are also provided.

“…Buckling Restrained Braced Frames (BRBFs) have been proved to be a reliable alternative to CBFs overcoming some of the deficiencies mentioned above. Since the inner steel core of Buckling Restrained Braces (BRBs) is laterally supported and restrained from buckling by the outer steel/concrete casing, their performance under compression is not limited by buckling, thus smaller yielding sections can be used unlike their conventional brace counterpart [8][9][10][11]. BRBs provide relatively large strength and stiffness under both tension and compression loads.…”
