PARAMETRIC STUDY OF DOUBLE LAYER STEEL DOME WITH REFERENCETO SPAN TO HEIGHT RATIO

AJIT S. PATIL AND H. S. JADHAV

Published By : Laxmi Book Publication

Abstract :

Optimum design of double layer dome of different span to height ratio(two cases- span to height ratio 2 and 4) and different supporting conditions(all bottom nodes supported, alternate bottom nodes supported and two alternate bottom nodes supported) for a given span is carried out. The formex programming software is used for configurations of double layer dome. The hollow circular pipe sections are used to construct the double layer dome and for connection, the MERO joint is used. Basically the dome have large exposed area there for the wind force are predominant, hence the domes are analyze and design for wind forces. For optimum design of the structure, it is analyzed by using the software “SAP-14”. In the analytical part, forces in the top layer are considered in groups and separate section will be designed for each group, the design will be based on IS800:2007. Similar procedure will be adopted for bracing system and bottom layer. The results are compared with different span to height ratios and support conditions for the deflection, weight of structure and concrete for pedestal, to determine optimum configuration by overall.
