Volume : II, Issue : XI, December - 2012 PARAMETRIC STUDY OF DOUBLE LAYER STEEL DOME WITH REFERENCETO SPAN TO HEIGHT RATIO![](ArticleImage/No_Image.jpg) 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. Keywords : Article : Cite This Article : AJIT S. PATIL AND H. S. JADHAV, (2012). PARAMETRIC STUDY OF DOUBLE LAYER STEEL DOME WITH REFERENCETO SPAN TO HEIGHT RATIO.
