In the current study, up to failure behavior of Hybrid Castellated Beams (HCBs) is predicted with use a developed Finite Element (FE) model. Both material and geometric nonlinearities are considered in numerical simulations. The accuracy FE model was validated using experimental test results presented literature. analysis had close agreement work predicting load mode pattern. A parametric study...

Abstract:   Previous research on bracing members show that the ductility of bracing members is compromised due to the buckling phenomena. Therefore, many researchers have tried to use special considerations to increase the fracture life of bracing members. Some of these recommendations such as increasing the slenderness ratio, using lower width to thickness ratio, increasing the out-of-p...

This study presents the results of large scale laboratory model tests to investigate the behavior of Compacted Lime – Well-graded Soil (CL-WS) rigid stone columns in soft soils. The  unit cell idealization is used for construction of composite specimens by evaluating the influence of different parameters such as the diameter of the column (D), the slenderness ratio (L/D) and the area ratio (Ar)...

The purpose of this study is to examine the vibration characteristics a rotating blade whose material distribution varies in spanwise direction. Formulations for functionally graded materials and beam structural models are carried out detail results displayed several figures tables which significant source information authors working area. Different parameters such as angular speed, radius hub,...

In this work, a comprehensive vibrational behavior analysis is performed on anti-symmetric laminated composite plates resting visco-elastic foundations undergoing thermal effects. Here, the governing equations of motion are developed through Hamilton's principle and Reddy's plate theory as higher-order shear deformation (HSDT) employed to capture high accuracy. Also, generalized differential qu...

This paper presents a numerical parametric study on design parameters of multispan viscoelastic shear deformable beams subjected to a moving mass via generalized moving least squares method (GMLSM). For utilizing Lagrange’s equations, the unknown parameters of the problem are stated in terms of GMLSM shape functions and the generalized Newmarkscheme is applied for solving the discrete equations...

We studied the influence of altitude on the spatial heterogeneity of tree diversity and forest structure in a subtropical evergreen broadleaf forest in southern China. Significant positive correlation was found between tree species diversity, basal area and altitude, but negative correlation between slenderness of trunks and altitude. According to topography, tree species diversity, diameter at...

We propose a new class of approximate local DtN boundary conditions to be applied on prolate spheroid-shaped exterior boundaries when solving acoustic scattering problems by elongated obstacles. These conditions are : (a) exact for the first modes, (b) easy to implement and to parallelize, (c) compatible with the local structure of the computational finite element scheme, and (d) applicable to ...

Abstract To analyze the reliability of slender columns subjected to axial force and uniaxial bending moment, with a slenderness index between 100 140, 216 were modeled. The square cross-section was adopted, three different configurations for longitudinal reinforcement. In calculation, general method linear creep theory applied. Several factors varied: index, reinforcement ratio, steel bars arra...

The paper aims to investigate the influence of characteristics strands on properties oriented strand boards (OSB). To solve this objective, some global synthetic (the slenderness ratio, thinness, and specific surface) four wood species currently used in technology (spruce pine for softwood, poplar willow hardwood) were first studied. OSB obtained from each separately also determined, finally co...
