Experimental and numerical investigation of post-tensioned concrete flat slabs in fire [PDF]

open access: yes, 2016
Purpose This paper aims to understand the structural fire performance of two-way post-tensioned flat slabs, particularly their deformations and load-carrying mechanisms in fire, and to explore the behaviour of post-tensioned high-strength self ...

Multi-Objective Optimization Design of FRP Reinforced Flat Slabs under Punching Shear by Using NGBoost-Based Surrogate Model

open access: yesBuildings, 2023
Multi-objective optimization problems (MOPs) in structural engineering arise as a significant challenge in achieving a balance between prediction accuracy and efficiency of the surrogate models, which are conventionally adopted as mechanics-driven models

Analytical Study of Punching Shear Capacity in Reinforced Concrete Flat Slabs with Opening Strengthened with Steel Plates and Shear Stud [PDF]

open access: yesپژوهش‌های زیرساخت‌های عمرانی, 2019
Reinforced concrete flat slabs are widely employed in structural systems. The location of the slab-column connection is the most sensitive part of the flat slab due to the existence of a high flexural anchor and shear force.

Comparative Analysis of RCC Flat Slab with Post-Tensioned Flat Slab

open access: yesInternational Journal of Scientific Research in Science, Engineering and Technology, 2019
A floor system plays an important role in overall cost and service of the building. Flat plate/slabs are economical since they have no beams and hence can reduce the floor height by 10-15%. In this paper analysis of RC flat slab with drop and post-tensioned flat slab with drop is carried out.

Analysis of the global tall buildings stability in flat slabs considering the soil structure interaction

open access: yesRevista IBRACON de Estruturas e Materiais, 2020
The global stability of tall reinforced concrete buildings made up of flat slabs is guaranteed, among other factors, by the existence of considerably rigid elements such as elevator cores and stairways.

Comparative Analysis of Mechanical Performance of Flat Slabs with Reverse and Conventional Column Caps

open access: yesBuildings, 2022
Compared with the conventional column caps, the reverse column caps that are used for slab-column joint of basement roof can improve the clearance of the basement while ensuring structural safety, and they are hidden in the covering soil without ...
