The efficiency of the use near-surface mounted (NSM) carbon fiber-reinforced polymer (CFRP) strips confined with CFRP wraps to strengthen reinforced concrete (RC) columns will be experimentally and analytically investigated in this paper. A total 15 specimens RC strengthened different numbers NSM-CFRP (0, 4, 8) 2, 4), prepared tested under concentric eccentric loading eccentricity ratios 0, 0.2...

Abstract Keramasan Bridge 2 is a bridge with an age of more than 30 years, so it necessary to review its feasibility and serviceability. Based on visual observations, there are signs cracks in the transverse longitudinal directions floor. results loading test, stated that deflection girder has exceeded allowable deflection, cause floor crack caused by non-uniform vertical movement girder. this,...

The mechanical response and fracture of metal sandwich panels subjected to multiple impulsive pressure loads (shocks) were investigated for panels with honeycomb and folded plate core constructions. The structural performance of panels with specific core configurations under multiple impulsive pressure loads is quantified by the maximum transverse deflection of the face sheets and the core crus...

This work presents continuous-flow particle sorting at low applied fields (as low as 30 V/cm) using electrodeless dielectrophoresis [2-7] in ridged polymeric microstructures. Particle manipulation and sorting is critical in the analysis of cellular systems and subpopulations, water monitoring, soil analysis, and colloidal synthesis. This technique is developed with a view toward sorting of cell...

Rotating shafts are important and responsible components of many machines, such as power generation plants, aircraft engines, machine tool spindles, etc. A transverse shaft crack can occur due to cyclic loading, creep, stress corrosion, and other mechanisms to which rotating machines are subjected. If not detected early, the developing shaft crack can lead to a serious machine damage resulting ...

Abstract—Punching shear failure is usually the governing failure mode of flat plate structures. Punching failure is brittle in nature which induces more vulnerability to this type of structure. In the present study, a 3D finite element model of a flat plate with low reinforcement ratio and without any transverse reinforcement has been developed. Punching shear stress and the deflection data wer...

This research a study transverse cracking that occurred on the floor structure of pile slab type bridge located at JORR W1 Kebon Jeruk toll road. The purpose this was to evaluate capacity had damaged by cracks and weather its remains are in safe condition or not. method is carried out analyzing calculation loading an actual cracked modeling structural analysis program with standard SNI 1725:201...
