    The reinforced concrete beam with lightning protection cable used in this research to determine the stress intensity and crack pattern of the beam. In this research, commercially available software developed by ANSYS used to model the nonlinear behaviour of reinforced concrete beams. The beam will model by using the ANSYS parametric design language (APDL). The beam structure was modelling in 3D geometry with the reinforcement steel bar and lightning cable embedded in the reinforced concrete beam structure. The material uses to develop the beam are Grade 30 concrete and high yield steel for main reinforcement. The material for lightning cable used was galvanized steel iron, which is highly resistance to corrosion and oxidation. The beam model in simply supported with pinned support at two end of beam and three-point load is applied. From the result beam added with lightning cable at bottom can sustain a higher stress intensity compare to the beam without additional lightning cable and beams without lightning cable have developed largest crack compared to the beam with lightning cable.

    Concrete prisms are being test with flexural testing by different percentage volume of steel fibres. The total number of 24 prisms were made which contain 3 %, 6 % and 9 % of steel fibres respectively. This only consist experimental results. Specimens used in this study using a prism mold of 100 mm x 100 mm x 500 mm. Eighteen prisms will be added with a layer of 10 mm of steel fibre using slurry method. All of the samples were tested using flexural testing to determine the maximum loading. The highlight scope of this research is to evaluate the physical behavior of Slurry Infiltrated Fibre Reinforced Concrete in term of maximum load and cracking pattern. The results of the study were also compared with concrete without steel fibres. However, the workability of the concrete decreased as the number of steels fibre increase. The maximum load was obtained by the lowest percentage of steel fibre (3%).

    Ultrasonic pulse velocity methods is one of the non-destructive testing methods. Commonly the compression test was used to determine the compression strength of concrete. Laboratory works had been carried out at heavy concrete laboratory to obtain the result for both non-destructive and destructive test. By using concrete cubes of sizes 100 x 100 x 100 mm and subjected to water curing for 7, 14, 21 and 28 days to obtained desire result for Ultrasonic Pulse Velocity and Compression test. Ultrasonic Pulse Velocity were initially done before the Compression test. The data obtained from each test has been evaluated and tabulated in this report. From this research, the variation between predicted strength and experimental strength for Ultrasonic Pulse Velocity testing was identified; the higher the pulse velocity, the higher the predicted strength and lower times passes by pulse velocity, the higher the predicted strength.
