Analytical and Finite Element Buckling and Post Buckling Analysis of Laminated Plates

Abstract

This examination is engaged into assessing the clasping heap of isotropic and overlaid plates (15 o /3o o /45 o /6o o ) which is exposed to in plane pressure. The investigation device utilized for this intention was ANSYS 19.0. The clasping load is assessed by changing the parameters, for example, angle proportion (a/b), thickness proportion (S) and limit conditions. It was noticed that diverse length to broadness proportion influenced the basic clasping load and the fiber direction edges likewise influenced the basic clasping load symmetric point employ plates.

End Detailing Experimental Study on the Seismic Performance of All-Steel Tubular BRBS

“…This damage mode can be avoided by applying reasonable construction measures. [4]. AST-BEBs with lid end connections serving as transitional regions (CP1-LBRB and CP2-LBRB specimens) generate better results than the other two proposed end details (PES-SBRB and NWS-BRB specimens) in terms of damage and rupture modes, hysteretic behaviors, stable and repeatable hysteretic curves, energy dissipation performance and compressive bearing strength.…”

“…For this reason, various types of BRBs have been examined by several researchers. In turn,(i) over the past thirty years the behaviors of such braces have been closely investigated both experimentally and numerically based on the hysterical behaviors of concrete-steel composition elements that can be useful in terms of energy dissipation [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]; (ii) many existing structures that are highly vulnerable to seismic events have been retrofitted with BRB systems [16][17][18][19][20][21][22]; and (iii) regulations and conditions common of their use are noted in modern seismic codes [23][24][25]. Most conventional BRBs are composed of an encasing core steel member confined by infill concrete and placed into a steel hollow structural section.…”
