This study investigated the seismic performance of cementitious grout filled coupler and sleeve connections in precast wall panels under cyclic lateral loading. The effectiveness these enhancing concrete walls was evaluated. In many countries, grouted are preferred option, whereas were more commonly utilized India due to belief that a greater portion dowel being enhances structural stability. T...

statement of problem: it is yet unclear whether fiber-reinforced composite posts can enhance the mechanical properties and prevent vertical fractures of teeth under chewing loads. purpose: the purpose of this study was to compare the fracture resistance and failure mode of endodontically treated teeth restored with three different post systems. materials and methods: thirty-six maxillary canine...

Trapezoidal prestressed unbonded retrofit (TPUR) systems have been recently developed and tested. The authors have already developed a comprehensive and accurate analytical solution for the TPUR system that takes many system parameters into account. The main aim of this paper is to develop a simplified analytical solution for predicting the behavior of metal beams that have been strengthened wi...

This article describes a numerical study for the evaluation of punching shear behavior non-adherent prestressed flat slabs without reinforcement. Nonlinear three-dimensional models were used, along with finite element method (FEA) through ATENA software in order to validate constitutive adopted concrete and steel. The results compared experimental results. revealed good agreement among load cap...

In the present work, a recently extended version of method dimensionality reduction (MDR) for layered elastic media is applied first time using semi-analytical approach. It based on priori knowledge cylindrical flat punch solution which determined numerically boundary element (BEM). We consider arbitrary indenters revolution producing circular area contact with bonded and unbonded layers thickn...
