Optimal RC networks for walls

PERFORMANCE BASED OPTIMAL SEISMIC DESIGN OF RC SHEAR WALLS INCORPORATING SOIL–STRUCTURE INTERACTION USING CSS ALGORITHM

In this article optimal design of shear walls is performed under seismic loading. For practical aims, a database of special shear walls is created. Special shear walls are used for seismic design optimization employing the charged system search algorithm as an optimizer. Constraints consist of design and performance limitations. Nonlinear behavior of the shear wall is taken into account and per...

Optimal Branching Structure of Fluidic Networks with Permeable Walls

Biological and engineering studies of Hess-Murray's law are focused on assemblies of tubes with impermeable walls. Blood vessels and airways have permeable walls to allow the exchange of fluid and other dissolved substances with tissues. Should Hess-Murray's law hold for bifurcating systems in which the walls of the vessels are permeable to fluid? This paper investigates the fluid flow in a por...

Non-rectangular Rc Walls: a Review on Experimental Investigations

When compared to tests on reinforced concrete (RC) walls with a rectangular or barbelled crosssection, only very few tests on RC walls with open cross-section exist. Most of these walls were subjected to unidirectional or bidirectional loading along one or both of the principal axes of the wall section. It was rare that tests were done using load paths that did not follow the principal axes. Th...

Seismic behaviour and analysis of U-shaped RC walls

In many countries of moderate to high seismicity, reinforced concrete (RC) core walls are used as lateral bracing systems in midto high-rise buildings where they typically accommodate lift shafts or stair cases. Unlike planar walls which provide horizontal strength and stiffness mainly in the in-plane direction of the wall, core walls provide bidirectional strength and stiffness. This feature c...
