Stability of SCSC Rectangular Plates under Intermediate and End Uniaxial Loads

Abstract

AbstractThis paper is concerned with a new buckling problem of rectangular plate subjected to uniaxial loads. The considered plate has two clamped edges parallel to x-axis while the other edges parallel to y-axis are simply supported (SCSC) subjected to combined uniaxial loads. The analysis of the plate under study is performed using minimum potential energy techniques andthe results are examined using finite element method. The energy method depends on the assumed deflection function, which satisfies exactly the end conditions and capable of representing the deflected plate surface. The analysis furnishes an approximate stability solutions; presented in curves describe the relation between the ratio of the intermediate load to the end load both, aspect ratio and the location of the intermediate load. These results can be used simply to design plates or walls that have to support intermediate floors/loads.Comparisons between the results of the energy technique and the finite element methods show very good agreement.
