Research Studies

This research studies the performance of Concrete Block Pavement (CBP) through the load distribution between the blocks and the jointing sand. Presence of jointing sand in joint provides frictional resistance to prevent the blocks from displaced or moved when the load is applied. Three different sizes of jointing sand (less than 2 mm, 5 mm and 7 mm) with three different jointing widths (2 mm, 4 mm and 6 mm) were used. Laboratory tests were conducted using horizontal load test to compare and investigate the effect by using different jointing sand sizes with different joint widths on the performance of concrete block pavement. It was found that the wider joint width requires coarse jointing sand for good performance of concrete block pavement. Results show that at 2 mm jointing width, it is more appropriate to use jointing sand with a size less than 2 mm and at a 6 mm jointing width it is better to use jointing sand with a size less than 7 mm. It seems to give better results in resisting the horizontal load that been applied before the blocks starts to displace and the pavement failed.

Piv Analysis

A suction pile is a promising option when floating offshore structures are deployed at deep and distant locations. A suction pile is typically used for the foundation system of a mooring system subjected to horizontal loading with a load inclination. In this study, the effects of installation method, loading position, and load inclination on the behavior of a suction pile under monotonic horizontal loading were evaluated via large-scale soil chamber testing. A series of horizontal load tests were performed by varying the loading position at pile embedded lengths of 1/4, 1/2, 2/3, and 3/4. A horizontal load test with a load inclination of 20° was conducted and compared with that of a load inclination of 0°. The failure mechanism of the suction piles under monotonic horizontal loading was assessed via particle image velocimetry (PIV) analysis. The movement of the suction pile during monotonic horizontal loading was elucidated in terms of the horizontal displacement, vertical displacement, and rotation angle. The results of this study show apparent differences between jacking and suction-installed piles and piles under different loading conditions. The PIV analysis shows that the rotational behavior under monotonic horizontal loading can be a critical point to affect the horizontal resistance of the suction pile.

Load Simulation

The purpose of this research is to reach good correlation between sun load simulation and solar focusing test for exterior automotive lighting products. Light coming from sun is highly collimated (parallel rays) and focusable from lenses with concave structure. Focusing incidence leads to a hot spot on lens surrounding plastic parts which may cause melting failures at high temperature zones. Sun load simulation is performing to eliminate risk of discoloration, deformation, out gassing, coating failures and fire with prolonged exposure from field. Irradiance values in W/m2 defined in simulation as heat source depending of an angle of incidence of the sun radiation. At first step, simulation is performing with 5 degree intervals to define the critical zones then intervals decreased to 2 degree to detect the critical azimuth and inclination angles. Critical azimuth and inclination angles is checking with ray trace analysis to check the bouncing of sun rays and possible solution to eliminate focuses with design solutions. After numerical analysis to release and validate the automotive lighting products regarding the sun load test, measurement with first parts is necessary. Measurement is performing for all critical angles which have been detected at simulation with thermal camera under ultra high-collimation solar simulator. Measured temperatures are settled according to environment conditions and correlation is checking with simulations.
