DESIGN OF CONOIDAL SHELL ROOFS

Abstract

The affect of i qth and lftb# the height rf crown at high end traverse and the heiit of crown at low ens traverse on the brane forces in parabolic ca!i t have been studjed. A computer progre a bee been foaulated for the bending analysis of parabolic eonodel ihell with edge bns with power Davies appxoech. The. calculations ns have been made by memo of X4 1620 Diqitel Computer. The msibrana forces have besn arrived at with +ss ed boundary con4itions. Ths aolut.on of mimbrane forces has ben attempted by rated of characteristic equations. Pay» long conoidal shells, whose length to width ratio is greater than one, the extensional forces in the l+ g.tu a direction are maore. For wide Conoid9, "fie length to width ratio is lose than os.,, the extensional forces in the transverse direc-tion jis $o t tt the ed a , thus transferring the loads; by arch action. in the ceding analysis the solution of di m. dial uxion of abal rw shall theory-basbeen done by power sris approach for the racial . deflection, atress function and estternal loa4.
