in this study, the performance of shred tire mixed with railway subgrade is evaluated to reduce environmental vibrations caused by trains’ passage. since incorporating the shred tire seeds in soil affects on its shear strength and deformability parameters so, the first stage of the study was allocated to conducting a series of laboratory tests such as the unconfined compression test, and cbr an...

This paper summarizes a series of studies on the interface of fiber reinforced polymer laminates externally bonded to concrete substrates, carried out in the Laboratory of Engineering for Maintenance Systems, Hokkaido University. Appropriate test methods and bond models for shear bond, tensile bond and cleavage bond (bond under dowel force) are shown. Finally, experimental results on shear bond...

With the aim of simulating the behavior of saturated sand with initial static shear (i.e., sloped ground) undergoing undrained cyclic loading, which leads to liquefaction and large cyclic shear strain development, an elastoplastic constitutive model which can describe both monotonic and cyclic torsional shear behaviors of saturated sand under drained and/or undrained conditions is presented. It...

The application of ECC materials in major stress and energy dissipation regions prefabricated reinforced concrete (RC) shear walls to form ECC/RC combined can improve the seismic capacity structures. damage mechanism a 1/2-scale two-story spatial structure specimen wall under low cyclic loading is numerically simulated. By comparing numerical simulation results with experimental results, correc...

in this paper, a thermoelasticity solution for steady state response of thick cylinders which are subjected to pressure and external heat flux in inner surface is presented. displacement field obeys the kinematics of the first order shear deformation theory (fsdt). it is assumed that the temperature varies both along the length and the thickness. the variation of the temperature occurs linearly...

Loading a specimen as shown in Figure 1a produces shear stresses in the material. An initially square element of the material, having vertical sides parallel to the direction of loading, is distorted by these stresses into a diamond shape as illustrated in Figure 1b, where the distortion is greatly exaggerated for pictorial clarity. Shear strain is defined as the magnitude of the change in the ...

The mechanical response and failure mechanism of commercially pure titanium subjected to combined tension-torsion loading are studied experimentally at strain rates ranging from 10?3 s?1 103 s?1. A novel split Hopkinson bar (TTHB) equipped with a high speed camera was utilised during high-rate experiments, while quasi-static tests were conducted using universal screw-driven machine. multiaxial ...

Dual systems of steel moment frame and reinforced concrete shear wall have combined the advantages of steel frames and reinforced concrete shear wall. These walls have increased the lateral stiffness of steel frames and have reduced seismic demands on steel frames thus providing opportunities to use such system. In this research intermediate dual system of steel moment frame was chosen with int...

A Trigonometric Shear Deformation Theory (TSDT) for the analysis of isotropic plate, taking into account transverse shear deformation effect as well as transverse normal strain effect, is presented. The theory presented herein is built upon the classical plate theory. In this displacement-based, trigonometric shear deformation theory, the in-plane displacement field uses sinusoidal function in ...
