Abstract: In recent times, there have been rapid changes in the Architectural design of multi-story buildings tending towards slenderer structures due purposely to space utilization. These changes are not without some inherent challenges on the serviceability requirements of these buildings; of major concern are deflection, oscillation, and excessive vibration developed by the action of wind on the structural members. This study carried out an evaluation of shear wall and frame network subjected to aerodynamic wind load on a 60m, 20 storeys regular building model for aerodynamic resistance of multi-story building with a view to having further improvement on the serviceability criteria............

Keywords: Shear-walls, Frame network, Aerodynamic, wind load.

Abstract: Computational fluid dynamic software ANSYS Fluent 15.0 is used to predict the physical parameters on the external surface of a vehicle. The simulation of the wind tunnel experiments using the above CFD package would be carried out. To study the aerodynamic influence of vehicle segments are considered as twobox form passenger car model (TOYOTA-Land Cruiser). As this model provided with the extremities in the design of vehicle category in summarizes these results in a broader sense to understand the aerodynamics of such profile. A wind tunnel experiments consists of physically testing the model in a simulated environment. It is a closed environment in which air is blown across the model at a constant velocity...............

Abstract: Computational fluid dynamic software ANSYS Fluent 15.0 is used to predict the physical parameters on the external surface of a vehicle. The simulation of the wind tunnel experiments using the above CFD package would be carried out. To study the aerodynamic influence of vehicle segments are considered as threebox form passenger car model (Mercedes). As this model provided with the extremities in the design of vehicle category in summarizes these results in a broader sense to understand the aerodynamics of such profile................

Abstract: Research is going on for efficient design to reduce weight of load carrying platform or panel. Various types of designs are used for different applications. Our main aim is to design panel at which can carry load at min weight .By reducing weight we save material cost and also other cost. All steel sandwich panel can be effectively used for general purpose applications of load carrying platform. Various types of core (i.e. stiffener) is possible. In this paper we have used rectangular steel plate as core and top bottom facings are also steel plate. Here, we have designed and optimized sandwich panel having 1mtr x 1mtr size for 1MT (10KN) load. We have discussed about important parameters of optimization for such panel and effect of change of these parameters on equivalent stress, total deformation and weight............
