The purpose of this work is to evaluate the most generally used techniques for measuring the thermal conductivity of concrete, as well as to consider the variables influencing the thermal conductivity of cement-based materials. Based on previous research indicating that the pattern of heat flow can be modeled in a numerical analysis program and provide a hue of coverage and differences in indoor temperature conditions, as well as the impact that occurs on several elements in the room, a heat simulation analysis was performed in this study due to a fire. The researchers in this study simulated the flow pattern from the temperature that occurred due to fire in a room measuring 4000x4000 mm with a wall thickness of 200 mm with Hebel/light brick material, floor plate thickness was 120 mm, and the size of the building column structural elements was 400x400 mm with the material reinforced concrete. According to the simulation results of a fire that occurred in the middle of the room with two conditions for installing hebel walls, namely covering the building structure columns and those behind the building structure columns, there is an increase in the temperature of the column with a ratio of 1.062 in the two conditions where the temperature of the wall lining the column is 6.28% lower than the temperature of the wall behind the column, while the heat flux magnitude that occurs is lower.

“…The studied prefabricated beam-column joints are about 80% similar to monolithic nodes regarding stiffness under lateral displacements and approximately 80% similar in terms of ductility. A Finite Element Analysis was conducted using the LS-DYNA software by Hussein M. Elsanadedy et al [7]. In their work [7], a numerical analysis using the Finite Element Method (FEM) was performed to assess the risk of progressive collapse at rigidified prefabricated concrete beam-column joints.…”

“…Many studies have been performed to investigate the contribution of structural members such as beams and columns in the vicinity of the removed column and the effect of different lateral bearing systems against progressive collapse [22][23][24][25][26][27][28][29][30]. In other studies, different types of progressive collapse analysis methods were investigated [31][32][33][34][35][36][37][38]. Several researchers investigated different types of beam-column connections on the response of concrete and steel structures against progressive collapse [39][40][41][42][43].…”

Diaphragms are a fundamental part of the earthquake-resistant system, and in terms of rigidity, it is essential to transmit dynamic loads on a base of the structure. Also, floor openings on the response of buildings against progressive collapse are issues that have received less attention. In this study, floor opening surfaces and their positions on the progressive collapse potential of steel moment-resisting frame (SMRF) buildings were investigated according to the alternate load path method. Moreover, to retrofit and rehabilitate the two-way reinforced concrete (RC) slabs against a progressive collapse, two strategies, prestressed concrete slabs and installing carbon fiber reinforced polymer sheets on the surface of the old concrete slab, were proposed and six-story SMRF buildings were simulated using the finite element method. The maximum axial force around the removal column is 20% greater than the corresponding values on the floor opening is in the corner of the plan and the appropriate performance of the prestressed concrete slab leads to the load distribution in the ceiling diaphragm.
