Unreinforced masonry (URM) walls strengthened with composites were tested to failure at a decommissioned building in St. Louis, Missouri. The walls were subjected to out-of-plane loading. Previous work on URM as well as reinforced masonry walls strengthened with FRP laminates has shown remarkable increases in capacity and ductility. However, most of this research work has been conducted in the ...
Objective: The objective is to obtain the stresses due to strip loading in orthotropic plate lying over an irregular isotropic elastic medium. Methods: Anti-plane strain problem with perfect bonding boundary conditions following by Fourier Transformation on the equilibrium equation are used to obtain the solution. The deformation field due to shear line load at any point of the medium consistin...
the aim of this research is to investigate the effect of carbon fiber reinforced polymer (cfrp) composite fabric on monotonic and fatigue behaviors of reinforced concrete beams. to control the failure occurrence, a small notch was induced at the middle span in bottom surface for all of the studied rc specimens. totally 12 beams were tested from which 6 beams tested under monotonic and 6 other t...
Plane-stress and shell macromodels are often preferred to analyze masonry structures because of their numerical efficiency. However, they misestimate the hysteretic behavior structures. Additionally, due nature smeared cracks, cracks may be diffused. This article proposes a new orthotropic model, which focuses on cyclic, nonlinear brick The model adopts total-strain based rotating crack approac...
We consider a nontrivial anti-plane shear fracture problem for a double-crack configuration where the remote external load is applied to the extracted mass-spring chain and the displacement field is symmetric with respect to the central axis between the cracks. An analytical solution obtained for the steady-state problem describes the displacement fields, stresses, local and global energy relea...
Experimental and numerical tests of the trap-door problem have been carried out, involving several granular materials. Three phases have been observed in the load transfer mechanism, as the trap-door is moved downward. The classical pattern for the description of this type of problem (a vertical plane of failure at each edge of the trap-door) corresponds to the third phase observed. The previou...
This note gives a necessary and sufficient condition that a compressible, isotropic elastic material should admit non-trivial states of finite anti-plane shear. One of the simplest classes of deformations of solids is that of anti-plane shear, in which each particle of a cylindrical body undergoes a displacement parallel to the generators of the cylinder and independent of the axial position of...
this paper presents a macro model to predict unreinforced masonry structures in plane behavior. the model is based on the concept of multilaminate theory. in the past, the method has been used to model behavior of soil, disregarding the cohesion and the tensile strength. regarding its mathematical base, and the possibility of applying in other cases, this method is used to predict the ultimate ...
We present the complete unfolding of streamwise localisation in a paradigm of extended shear flows, namely, two-dimensional plane-Poiseuille flow. Exact solutions of the Navier-Stokes equations are computed numerically and tracked in the streamwise wavenumber Reynolds number parameter space to identify and describe the fundamental mechanism behind streamwise localisation, a ubiquitous feature o...
objective: the objective of this study was to investigate the invitro fluoride release of four new self-adhesive resin cements; set (sdi, australia), breeze (pentron, usa), embrace wetbond (pulpdent, usa), g-cem (gc, japan) and to assess the bonding performance of these self-adhesive resin cements for bonding of orthodontic brackets. materials and methods: for fluoride release experiment, six ...
