Sandwich beams comprising identical face sheets and a square honeycomb core were manufactured from carbon fiber composite sheets. Analytical expressions were derived for four competing collapse mechanisms of simply supported and clamped sandwich beams in three-point bending: core shear, face microbuckling, face wrinkling, and indentation. Selected geometries of sandwich beams were tested to ill...
Background and Aim: Clinical guidelines are categorized and provide information in order to help the decision-making of medical teams, with the aim of improving patients care. Therefore, this study aims to identify the factors influencing the implementation of clinical guidelines in Iran. Methods: This is a descriptive-analytical study performed in 2018‒2019. The study population consisted of m...
Plinian and subplinian volcanic eruptions can be accompanied by tephra falls which may last hours or days, posing threats to people, buildings and economic activity. Numerous historical examples exist of tephra damage and tephra casualties. The mechanisms and consequences of roof collapse from static tephra load are an important area of tephra damage requiring more research. This paper contribu...
The non-linear programming theory along with active set algorithm is employed to solve the objective function of quadratic type problem in soil mechanics under plain strain and two dimensional loading conditions. Combination of lower bound limit analysis and finite element method leads to an appropriate procedure for determining the collapse load of the system. In this combined method, a linear...
The current design method of ultimate capacity beam string structure (BSS) is mainly based on the fixed load ratio (FLR) criterion, seldom considers effect random (RLR) bearing capacity. This paper compared coefficient variation (COV) obtained by RLR criterion with that FLR criterion. It indicates properties have a significant impact COV and should be accounted for. A more realistic limit state...
