Abstract Self-compacting concrete (SCC) is the most flowable concrete type that exerts high pressure on formwork. SCC is the most commonly used concrete globally for construction applications due to its cost-effectiveness. However, to make a formwork resist the exerted lateral pressure of SCC, it is required to have a suitable design for formwork. This paper presents a novel approach on how could create and prepare the Fiber Bragg Grating (FBG) optics using as a sensor to measure lateral pressure and temperature of SCC. To ensure the FBG sensor works properly a validated methodology is conducted. In More > Graphic Abstract

Abstract In this paper, the densely arrayed bonded particle model is proposed for simulation of granular materials with discrete element method (DEM) considering particle crushing. This model can solve the problem of pore calculation after the grains are crushed, and reduce the producing time of specimen. In this work, several one-dimensional compressing simulations are carried out to investigate the effect of particle crushing on mechanical properties of granular materials under a wide range of stress. The results show that the crushing process of granular materials can be divided into four different stages according to e_r-logσ_y curves. At More >

Abstract The aim of the present paper is to develop a semi-analytical method which and quickly and accurately compute the ultimate strength response of rectangular plates under combined loads and non-uniform lateral pressure. It is assumed that the plating is simply supported at four edges which are kept straight. A unique feature of developed method was found to give reasonably accurate results for practical design purpose in terms of the large deflection analysis of plates under non uniformed lateral pressure. The present paper treated by analytically solving the nonlinear governing differential equations of the elastic large More >
