Abstract Objective: Endodontically treated teeth with inadequate crown structure need a radicular post to help restore the tooth to proper function. Therefore, finding an efficient and timely method for preparing the post space in a way that causes less change in the amount of apical flood of the canal, has been the subject of various discussions and researches for many years. In this study, ...

Calculation of lateral earth pressure on retaining walls is one of the main issues in geotechnics. The upper and lower bound theorems of plasticity are used to analyze the stability of geotechnical structures include bearing capacity of foundations, lateral earth pressure on retaining walls and factor of safety of slopes. In this paper formulation of finite element limit analysis is introduced ...

The compound strip method (CSM) for plates is an expansion of the finite strip method (FSM) and was developed to incorporate the effects of the support elements in the analysis of linear elastic plate systems. In this paper the CSM is further expanded to analyze structures such as stiffened plates under loads in the plane of the plate or the so called plane-stress condition. Examples of these t...

This paper proposed a novel supporting and retaining structure used to high-steep building slope reinforcement. It combined with an anti-sliding pile inclined column, which is as fulcrum on the upper part of pile. The mechanical characteristics are studied firstly by two methods numerical methods, respectively. Result shows that axial force will be evenly distributed along column body it provid...

Abstract Variation laws of earth pressure accounting for the displacement are taining wall can be well described by mathmatical fitting in study relationship between and retaining displacement. The common mathematical function expressions divided into sinusoidal model, exponential like hyperbolic semi-numerical semi-analytical model function, etc. characteristics shortcomings current expression...
