Domain size for 3D numerical simulation in ANSYS CFX was taken from previous study. To determine optimum length of building for accurate prediction of pressure distribution at mid length of long structures a comparative study has been carried out with same model but with different length. After determining optimum length of the structure a parametric study has been carried out to understand effect of different geometrical parameters on the pressure distribution around the structure. Effect of H 2 /H 1 ratio, S 1 /S 2 ratio and roof angle on the pressure distribution is studied in this study.

Parametric sets required for various input and output parameter were defined and used in ANSYS® Design Exploration tools. Lastly, Optimization is performed in ANSYS ® workbench using Response surface optimization tool. The Optimized weight and the corresponding member sections extracted from this optimization is presented. Index Terms-Optimization, Geodesic steel dome , JAVA Scripting , ANSYS ® Workbench , Response surface , A dome is one of the oldest structural forms and it has been used in architecture from earliest times. Domes are of special interest to engineers and architects as they enclose a maximum amount of space with a minimum surface and have proved to be very economical in the consumption of construction materials. A dome is been proved as a most efficient self-supporting structure for a large area due to its two curved direction. Architect and engineers have been excited about the possibilities of space structures for the past many years. They offer opportunities for variation in plan form and building profile, large uninterrupted spans, and excellent distribution of loads, optimum utilization of materials and prefabrication and mass production of easily transportable components. Now that the computers are readily available to handle the complex calculations, there should be little implement to the widespread use of these interesting structures. Domes and shells have an outstanding role in modern construction. Domes can be exceptionally suitable for covering sports stadia, assembly halls, exhibition centers, fish farming aqua pods, swimming pools and industrial buildings. For getting large unobstructed areas with minimum interference from internal supports. A dome is a typical example of a synclastic surface in which the curvature of any point is of the same sign in all directions. The synclastic surfaces are also called surfaces of positive Gaussian curvature and are not developable, that is, a domic surface cannot be flattened into a plane without stretching or shrinking it. This property is one of the reasons why, in practice, domes cannot be built from me mbers of the same length. Geodesic domes constitute an important family of braced domes offering high degree of regularity and evenness in stress distribution. Data preparation and handling of graphics for geodesic forms are difficult and time consuming tasks and are the stages of analysis where mistakes are most commonly made.

Shear wall stabilise the whole structure against the effect of strong horizontal seismic loading. Shear wall is usually used for high rise building and excellent performance is achieved. The main goal of this research is to find out up to which base dimension the effectiveness of shear wall is maintained. The present study is an attempt to understand the effectiveness of shear wall on different aspect ratio of building (H B /L B ). Three different aspect ratio of building (R= H B /L B i.e. 1,2,3) has been taken. The effectiveness has been checked up to G+30 storey building with every five incremental storey. To avoid torsional behaviour, symmetrical building with rectangular type of shear wall at the center of face of the building on both directions building was taken. The shear wall dimensions were restricted by shear wall aspect ratio (H w /L w ).The response spectrum analysis of building without shear wall and with shear wall was carried out using ETABS ® software. At the end, building response parameter Displacement was compared.

Pultruded I-beams are manufactured using fiber and matrix composite lamina hence is usually orthotropic compared to conventional steel I-beams. Many researchers have studied the buckling characteristics of simply supported pultruded FRP beams for various types of loadings. In this paper an attempt has been made to study the buckling characteristics of cantilever beam subjected to point load at free end for WF(wide flange) & NF(narrow flange) section. The validation has been made with experimental data. Further the parametric study has been carried out to study the effect of fiber orientation along with fiber volume fraction on critical buckling loads.
