This study investigates the complex load-bearing mechanism of reinforced concrete tower large wind turbines through a structural model test. MTS electro-hydraulic servo loading system was used to load two models for push-out The ultimate bearing capacity found be 8.894 kN. test findings revealed that top is subjected unilateral shear as horizontal increases. As result, strain in compression zon...

Bending tests were conducted on ferrocement laminates containing chicken mesh and steel slag. The fundamental goal of the examination was to investigate effects partial substitution fine aggregate by slag in cement mortar combining different volume fractions as reinforcement thin laminates. following variables investigated: (a) fraction 0.94%, 1.88%, 2.82%, 3.77% (b) level from 0% 50% weight ag...

We evaluated mechanical properties (first matrix cracking stress, strength, and work-of-fracture) of Nicalon-fiber-reinforced silicon carbide matrix composites with three different fiber lay-up sequences (0"/20"/60", O0/4Oo/6O0, and 0"/45") at various temperatures from room to 1300°C. Up to 1200"C, ultimate strength and work-of-fracture for the 0"/40"/60" and 0"/45" composites increased, but th...

To study the axial compression performance of a steel-reinforced ultra-high-performance concrete-filled square stainless-steel tube (SR-UHPCFSSST), eight specimens were designed with different length-to-diameter ratios and skeleton contents, tests numerical simulations performed. Damage pattern, ultimate load capacity, load–displacement curve data obtained. Finite element analysis was performed...

Abstract To study the effects of macro- and micro-fiber on concrete beams, bending resistance tests were conducted polypropylene fiber-reinforced beams. Stepwise loaded carried out to obtain load–deflection curves for different test pieces, cracking load values first inclined crack, recording depicting crack development, changes in mid-span deflection load–strain relationships concrete, etc. Th...
