“…However, in the case of uneven distribution of strength or stiffness and discontinuity of the structural system, irregularities in the structure can occur [10][11][12][13]. Facilities of more complex configuration [14,15] and foundations require more complex constructive solutions, more materials, labor, construction logistics and time [16][17][18][19].…”

Fire protection of facilities is basically based on passive and active form. Given that active forms have a limited role in the early stages of fire, the decisive role in preventing the spread of fire, until the arrival of emergency firefighting units, have elements of passive protection at the facility. The topic of this paper is facades in residential buildings and their role in spreading fires throughout the building. The aim of this paper is to design one of the possible models for choosing the optimal façade shape (or the facility), which would passively prevent the transmission of fire over the facade. For these purposes, an analysis of key aspects was performed, which, in addition to fire resistance, considered seismic resistance and energy efficiency, both dependent on the shape of the facility. The obtained results are valorized through a quality scale, based on which is determined whether the solution is bad, acceptable, satisfactory, or good. This model contributes to a quality and controlled design process, because the concept of a facility, that meets the requirements of modern construction, is obtained at an early stage. The practicality of this model is reflected in the fact that, on the one hand, in the design phase it allows to bring more variant solutions at the same qualitative level, and on the other hand it is applicable to already constructed facilities, which indicates shortcomings and possibilities of their reconstruction.

There is a common practice of extending the cantilever beams/slabs on the upper floors of a building in Nepal either to increase the room size or for aesthetic purposes. It ignores the increased seismic effects due to asymmetry. In most cases, reinforced concrete frame structures are designed without cantilevers. However, in reality, it’s not always the same. Hence, the assumed effects during the structural analysis do not reflect the real behavior of the built structural system. This study aims at presenting the effects of cantilever projections in the seismic response parameters of regular RC frame building. For this, 3 and 5 story regular RC buildings along with 3 feet, 4 feet, 5 feet and 6 feet cantilever projections on one and two facades are selected resulting to a total of 18 models. All the models are analyzed using Response Spectrum Analysis method. The results demonstrate that the cantilever projections in regular building cause the significant increment in the seismic response parameters. The fundamental time period is increased by 10.93%, the base shear by 19.67%, the inter-story drift ratio by 52.57% and the overturning moment by 20.36% upon increase in mass by 19.69% due to cantilevers. The torsional moment in column is increased by 3.53 times and bending moment in column by 1.5 times whereas the cantilever deflection has exceeded the allowable limit. Therefore, proper engineering analysis and design is essential for cantilevers to ensure the overall safety and performance of the structure during seismic events.
