Band clamps with a flat bottomed V-section are used to connect a pair of circular flanges to provide a joint with significant axial strength. Despite the wide application of Vband clamps, their behaviour is not fully understood and the ultimate axial strength is currently only available from physical testing. This physical testing has indicated that the ultimate strength is determined by two di...

This article presents an experimental investigation on the bending capacity of steel-concrete composite truss girder (SCCTG). Four full-scale specimens named CB1, CB2a, CB2b and CB3 respectively, are tested and numerical analyzed. Stress distribution, load-displacement relationship, load-slip relationship and ultimate bending capacity of SCCTGs are investigated. The results show that SCCTG foll...

Abstract Concrete-filled steel tube columns are widely used in civil engineering structures due to their excellent ductility, energy absorption capacity, ultimate load-bearing and seismic behavior. In this paper, a numerical study modeling of eight lightweight concrete conventional filled tubes was carried out using ABAQUS software, the lateral load-carrying capacity square circular under cycli...

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...

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...

Lattice boom used on the crawler crane are welded by slender high strength steel tubes. Many studies show that actual bearing capacity of high-strength tubes is higher than stability calculated according to specification. To obtain and apply it engineering practice, a series axial loading tests carried out two kinds 20Mn2 S890 their damage load. By handling test data, coefficient fitting correc...

The reliability index is an important reliability parameter that is necessary for the development of reliability-based geotechnical design. Both the factor of safety (FS) and the reliability index (β) represent safety margin of structures against either failure or limit state. In this study, the reliability index is analyzed and evaluated in reference to the factor of safety currently adopted i...
