This paper presents the study of strengthening R/C beams with large circular and square opening located at flexure zone by Carbon Fiber Reinforced Polymer (CFRP) laminates. A total of five beams were tested to failure under four point loading to investigate the structural behavior including crack patterns, failure mode, ultimate load and load deflection behaviour. Test results show that large o...

Load carrying capacity of flat double-layer space structures majorly depends on the structures' imperfections. Imperfections in initial curvature, length, and residual stress of members are all innately random and can affect the load-bearing capacity of the members and consequently that of the structure. The double-layer space trusses are susceptible to progressive collapse due to sudden buckli...

The restoration of strength and stiffness of damaged reinforced concrete beams with deficient reinforcements, through retrofitting, was experimentally and numerically studied. Retrofitting is carried out by wrapping glass fiber strips using cement-based composite binders. Six beams of size 1500mm (length) x100mm (width) x 150mm (depth) have been tested in four-point bending. Three beams are use...

This paper presents the bearing capacity determination of strip footing placed on sand underlain by clay and subjected to inclined loading. The equation is derived within framework limit equilibrium following projected area approach. inclinations load spread were selected performing an additional finite element analysis. A parametric study was conducted highlight effect various input parameters...

Abstract in geotechnical engineering, foundation piles are ideal for deep foundations that cannot bear higher loads. This architectural expansion places a great deal of responsibility on the engineer to anticipate appropriate load constructor. Unfortunately, calculations pile’s bearing capacity not accessible. It has always been source concern engineers, as structure’s safety depends and gives ...

3D braided composite joints are the important components in CFRP truss, which have significant influence on the reliability and lightweight of structures. To investigate the mechanical performance of 3D braided composite joints, a numerical method based on the microscopic mechanics is put forward, the modeling technologies, including the material constants selection, element type, grid size, an...
