Throughout history, earthquakes have posed a substantial risk, leading to extensive devastation and tragic loss of human lives. Repeated earthquake activity can be particularly concerning as it can lead to further damage and destruction. Hence, implementing approaches aim at enhancing a building’s resilience to seismic activity and mitigating the d...
Countries that experience regular earthquakes with magnitudes greater than 7 on the Richter Scale are currently recognized to suffer significant destruction. These unpredicted calamities can have detrimental effects on both people and structures. However, by identifying the threat that might be damaging the current structures, the effect of seismic...
A seismic event is unpredictable and may occur worldwide depending on the movement of the fault line. The impact of this phenomenon on society, structures, sources and surroundings is significant to be investigated. Thus, this study aims to investigate the seismic awareness level and input information among Malaysians. Several far-field seismic act...
Since the cost of cement increases and the pollution to environment due to greenhouse effect are becoming more serious year by year, thus, dolomite fines subjected to replace the cement in concrete mix as it has lower cost compared to cement.

80% of the water supplied, normally comes out as wastewater either domestic or industrial. The utilization of wastewater in concrete will reduce potable water usage in the construction industry. Approximately 150 litres of water are required for lm ³ of concrete without considering other applications of water in the concrete industry. This research...
The method of Spectral Analysis of Surface Wave (SASW) is a seismic method that consider as a non-destructive geotechnical technique to determine the soil profile based on the shear wave velocity profile by utilizing the dispersive characteristic of Rayleigh wave through the soil medium. The shear wave velocity was found to be directly proportional...
The use of waste products as partial replacement for the material in concrete can help to reduce the environmental and economic problem. Coconut shell (CS) is one of the agricultural waste that suitable to use as and coarse aggregates replacement due availability of CS which not only can help to decrease the cost of the concrete and reduce the envi...
This study was related to the application of lake water in the production of concrete samples as partial replacement to freshwater. The effect of the applications in terms of concrete properties were determined and compared with normal concrete samples that were cast with fresh water. The lake water was collected at Tasik Timah Tasoh, Perlis. In th...
Seismic effect to the tunnel form building (TFB) will vary depending on the location of the epicentre, magnitude and frequency of the seismic event. This effect can be mitigated by implementing a seismic analysis using the Ruaumoko 2D programme. The seismic analysis was conducted to examine the safety level of the TFB when it was subjected to 10 pr...
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...
Recently, the agricultural waste have been enticed increasing attention in geotechnical engineering as a natural soil reinforcement in improving strength and stability of soils. Agricultural waste fiber was chosen as it is cheap, locally available, bio-degradable and eco-friendly. In this study, the implementation of banana fibers has been used as...
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 w...
Clay soils are considered as a problematic soil in term of water absorption rate. The ideas of soil improvement method had been widely used to modify the physical and mechanical properties of clay soil. This study aims to identify the optimum percentage mixing of natural fibers in influencing the compaction characteristics. X – ray fluorescent test...
To date, frequent seismic events are seen to cause major destruction to the countries that are hit by great Earthquake with magnitude greater than 7 Scale Richter. These kinds of disasters are unpredicted and may give negative impacts for structures and human. However, the consequences of seismic can be mitigated by characterizing the hazard that m...
The Polyethylene terephthalate (PET) waste flake was used in concrete with partial replacement of 15%, 25% and 35% by volume of conventional fine aggregate. Four batches of concrete specimens including one without plastic aggregate, for comparison purpose, were prepared. All the concrete specimens were tested for its different mechanical properties...
Tunnel form building is frequently utilised by contractors and developers in constructing high rise building due to its rapid construction process and cost-effective method. However, the capability to cater earthquake load is still questionable. In Malaysia, most of the existing buildings were constructed using BS8110 without any provision to earth...
Steel is one of the fibers used in fiber reinforced concrete technology. Steel fibers in concrete help to improve flexural strength and crack resistance.
