Several deficient steel structural members require to be strengthened all over the world. In this article, horizontal defects were generated at three locations (top, middle, and bottom) on the middle element and the middle of the side element. Consequently, the effects of the location of such defects on axial behavior of Carbon Fiber Reinforced Polymer (CFRP) strengthened steel Square Hollow Se...

OBJECTIVE To obtain the compressive load bearing and energy absorption capacity of lumbar vertebrae of osteoporotic elderly for the everyday medical praxis in terms of the simple diagnostic data, like computed tomography (CT), densitometry, age, and sex. METHODS Compressive test of 54 osteoporotic cadaver vertebrae L1 and L2, 16 males and 38 females (age range 43-93, mean age 71.6 ± 13.3 year...

Increasing the cross-sectional area of piles or adding wings to are two strategies for increasing bearing capacity resist lateral stresses. Small and full-scale finite element models were used investigate effect on laterally loaded pile in this study. Four embedded ratios (4, 6, 8, 10) with various wing dimensions numbers. The results showed that increases resistance loads reduces displacement ...

This paper presents a numerical study of 3×3 pile groups embedded in clay under vertical and inclined eccentric loads. Simplified modelling, based on elastic beams soil continuum, is used to explore the soil-pile-cap response. simple model allows rigorous treatment 3D foundation geometry local plasticity, demonstrated through validation with finite element analysis. The results reveal that comp...

The axial compressive behavior of laminated bamboo lumber (LBL) columns with a chamfered section was investigated using 15 specimens lengths varying from 600 mm to 3000 mm; all considered samples had same square cross 100 × 10 chamfers at each corner. Axial compression tests were carried out analyze the impact slenderness ratios on failure modes, strain and ultimate bearing capacity LBL columns...

Nonlinear finite element simulation was once employed to look into the behavior of horizontally curved reinforced concrete deep beams under concentrated load at its mid-span. The study focused on parametric impact span length-to-depth (L/D) and length-to-radius (L/R) ratios. In addition, effect longitudinal spacing shear reinforcement beam has been investigated. considered sixteen specimens. Th...

BACKGROUND Intramedullary (IM) nailing is the treatment of choice among orthopaedic surgeons for tibial shaft fractures. However, because of the close proximity of the nail's insertion site to the anterior medial (AM) meniscal root on the tibial plateau, there is increased risk of iatrogenic injury to the meniscal root during nailing. PURPOSE To quantify the area of the AM meniscal root footp...

according to non-existence of accurate inspection tools on various steps of design and construction of buildings in the past, also due to any change in function of some structures and finally of seismic activities of residential regions of the country, vulnerability assessment of existing structures is necessary. evaluation of vulnerability of the structures is classified in two categories, qua...

concrete shear walls are the most prevalent structural systems resisting lateral loads due to earthquakes in high-rise buildings. very large in-plane stiffness of shear walls provides an excellent drift control in the structure. however, structural damages and early code shortcomings threaten the efficiency of existing structural walls against earthquake. recently, fiber reinforced polymer (frp...

Geopolymer concrete is preferred over OPC due to its use of energy waste such as fly ash, making it more sustainable and energy-efficient. However, limited research has been done on seismic characterization in confined masonry, highlighting a gap earthquake-resistant structures. Our study compares the performance alkali-activated fly-ash-based geopolymer bare frame masonry wall panels with conv...
