Strengthening of the existing seismically deficient reinforced concrete (RC) buildings is an important issue in earthquake prone regions. Addition of RC shear wall as infill or external walls into the structural system has been a commonly preferred strengthening technique since the Big Erzincan Earthquake occurred in Turkey, 1992. The newly added rigid infill walls act primarily as shear walls ...

We present a Lagrangian-Lagrangian approach for the simulation of fully resolved Fluid Solid/Structure Interaction (FSI) problems. In the proposed approach, the method of Smoothed Particle Hydrodynamics (SPH) is used to simulate the fluid dynamics in a Lagrangian framework. The solid phase is a general multibody dynamics system composed of a collection of interacting rigid and deformable object...

An ideal I on a cardinal κ is called rigid if all automorphisms of P (κ)/I are trivial. An ideal is called μ-minimal if whenever G ⊆ P (κ)/I is generic and X ∈ P (μ)V [G] \ V , it follows that V [X] = V [G]. We prove that the existence of a rigid saturated μ-minimal ideal on μ+, where μ is a regular cardinal, is consistent relative to the existence of large cardinals. The existence of such an i...

Abstract We study the effect of isotropic porous walls on a plane Couette flow laden with spherical and rigid particles. perform parametric varying volume fraction between 0 30 % , porosity 0.3 0.9 non-dimensional permeability 7.9 × 10 - 3 find that induce progressive decrease in suspension effective viscosity as wall increases. This behavior is explained by weakening wall-blocking appearance s...

The objective of this paper is to study the elastic seismic response simplified building models that include considerations vertical lateral force resisting system (walls) and horizontal (floor diaphragms) through parametric study. assumption rigid diaphragms often used in design buildings; however, research suggests diaphragm may influence fundamental period response. In paper, a model present...

A common lateral force resisting system for cold-formed steel (CFS) buildings consists of shear walls sheathed with oriented strand board (OSB). Previous experimental and computational research on CFS shear walls, as well as those with other framing materials, has demonstrated that the complex interaction of the fasteners with the sheathing is an important factor in the nonlinear behavior of th...

The deformation failure modes of gravity retaining walls include overturning, toppling, deep sliding, and eccentric failure. complex mode, which involves the multi-stage walls, suffers from a lack mechanical models design theories. Based on basic theory reinforced concrete construction, this study established calculation model bottom-confined (RC-GRWs), are composed tensile, compressive, rigid ...
