Primary load-bearing members used in glass structures, such as columns consisting of panels, are frequently subjected to in-plane loading. Its allowable stress for safety design appears be a significant subject. By analyzing the results static (without repeated loading) and cycling compression loading tests, authors explore mechanical features failure mechanism tempered panels subjective loadin...

In the seismic performance assessment of reinforced concrete (RC) frames, a reliable estimation capacity unreinforced masonry (URM) infill walls is utmost importance to ensure structural safety conditions. With particular attention out-of-plane (OoP) URM after in-plane (IP) damage, issue defining analytical prediction models for an ongoing study. this paper, empirical equations are proposed eva...

The buckling of compression members may lead to the progressive collapse spatial structures. Based on sleeved member, monitoring member is introduced control and raise alert by sensing contact between core tube restraining tube. Considering rigid connection among in structures, with ends needs be further analyzed. An experimental test was conducted finite element analyses were performed calibra...

The fracture process in self-healing concrete with embedded brittle capsules entails challenges terms of understanding how and when these break to release the agent. This paper presents a combined experimental–numerical investigation which versatile three-dimensional simulation model is developed investigate this type beams under three-point bending load. allows for correlating overall strength...

A new finite element (FE) model was constructed with ABAQUS, and the applicability of verified by coincidence typical damage modes load-compression curves in tests, axial compression performance precast circular semi-continuous concrete-filled steel tube (PCSCFST) columns investigated. The effects diameter-thickness ratio, slenderness yield strength, etc. on PCSCFST were investigated parametric...

The natural frequencies and damping rates of surface waves in a circular cylinder with pinned-end boundary conditions are calculated in terms of the gravitational Reynolds and Bond numbers, C and B, and the slenderness of the cylinder A, in the limit C —>• 0. We consider higher-order approximations that include the effect of viscous dissipation in the Stokes boundary layers and the bulk. A comp...

The influences of curvatures and of physical properties on the mechanical stability of the spine were analysed by means of a three-dimensional, geometrical, nonlinear biomechanical model. According to the model, the initial buckling load decreases with increasing lordotic and kyphotic curvatures. When the body weight is taken into account as a load distributed along the whole spine, the calcula...
