The research carried out to study on the performance of the flat slab under the design load. The design loads consist of service load, 14.68 kN/m2 and the ultimate load, 21.31 kN/m2. The justification on the design load was from the car park. The Three-Dimensional (3D) Finite Element Analysis (FEA) were conducted to investigate their failures modes with the appropriate modelling of element, mesh and concrete parameter. The size of flat slab was 1200 mm x 1200 mm x 175 mm while the material parameters were the Grade 25 for concrete and S275 for steel. It is found that the improvements more than 20% to the strength of model flat slab with shear reinforcement. Another outcome of the study indicated that the punching shear location using the FEA was less than 250 mm from column perimeter which is within the two times the depth (2d) from column face as proposed by the Eurocode 2: Design of Concrete Structures.

Load-Displacement Behaviors of Reinforced Concrete Beam Embedded with Galvanized Steel Cable: Comparison Between Experiment and Finite Element Analysis

2020-01-01 , Mustaqqim Abdul Rahim , Abdul Ghani A.N. , Muhammad Arkam Che Munaaim , Zuhayr Md Ghazaly

Lightning is a natural phenomenon which occurred when the upper atmosphere becomes unstable due to rising air currents. Lightning can be one of the natural causes of human injuries or damage to electrical equipment. In order to create a system to protect buildings from this natural phenomenon, the Lightning Protection System (LPS) was introduced. However, various problems have been associated with this conventional method. A common problem related to external lightning protection cables is corrosion. Therefore, the newly arrangement of lightning protection cable was proposed and investigated. Galvanized steel cable was used in this research due to suitability of the materials to be embedded inside reinforced concrete beam. Load-displacement behavior from the three (3) point flexural test was compared with the finding from the Finite Element Analysis (FEA). From the result, FEA showed slightly higher than experiment result at the maximum load.
