Analysis of prestress concrete highway bridges with and without rubber bearing

Malaysia has been using bridge rubber bearing in their practices to isolate vertical vibration from the movement of traffics. The bearings placed between the bridge decks and the upper side of columns are constructed to make sure the loading couldn’t affect the overall structure of bridge and other structures. In structural earthquake engineering, natural rubber and steel are used mainly in base isolator that is one of the energy dissipation systems to reduce earthquake effect on structures. With laminated natural rubber and steel, the bearing can provide very high vertical stiffness and very flexible in horizontal direction to make sure the mounts can support the loading from the structure and prevent excessive sideways from any horizontal loading especially when earthquake occur. Most bridges in Malaysia are multi-span simply supported where due to impact at the joints. In the design guidelines clearly state that, in Malaysia, no seismic consideration in bridges designing especially for JKR bridges. This study try to analyse the common JKR Bridge fewer than two types of Earthquake ground motion (San Fernando and El Centro Earthquake) and also Truck load. The overall objective of this study was to evaluate the linear response spectrum analysis of actual bridge: i.Evaluate the combined effect of longitudinal and transverse earthquake excitation on the response of actual JKR bridge using 2-D and 3-D models, ii.Determine the capacity/ demand ratios for various bridge components using JKR guidelines, and iii.Recommended possible modifications to the design of new bridges and response possible retrofit procedures for existing bridges

Inter-Row Tree Detection and Tracking Schemes For Structural Plantation Area

In this work, an inter-row tree detection and tracking techniques based on Simultaneous Localization and Mapping (SLAM) method is developed specifically for a well-structures agricultural field where the trees are planted uniformly with certain distance that leaves it with a number of inter-row spaces. The existing rows has created opportunities for an autonomous vehicle to navigate in between the trees to perform the plantation activities such as scouting, monitoring, rowing, pesticide spraying and others. A new approach to detect the landmarks and navigate in the farm based on the lightweight sensors and less computation effort is proposed. In this method, the tree detection and diameter estimation techniques implement the modified tree-triangle diameter technique by using innovative technique based on infrared sensors. Then, in substituting the GPS signal problems during the navigation and localization problems, a curve-based navigation approach is formulated. The path is planned based on the third-polynomial Bezier curve by projecting series of waypoints to create a solid path from one point to another. Then, the trajectory plan is derived for the autonomous vehicle to follow these waypoints during the navigation. At the same time, the mapping technique implements the memory utilization method in order to ease the localization process as well as landmarks mapping in the visual map which is oriented in two-dimensional coordinate format. All of these functions are created, formulated and tested thoroughly in the embedded microcontroller development board platform by using dsPIC30F6014A chip on the omnidirectional vehicle platform
