摘要:A class of fiber-reinforced concrete, commonly called strain-hardening cementitious composite (SHCC), can show very ductile behavior under tension. In the post-cracking stage, several cracks develop before complete failure, which occurs when tensile strains finally localize in on...

摘要:The ductility of high-performance fiber-reinforced cementitious concrete (HPFRCC) can be developed not only in tension but also in compression. This aspect is evidenced in the present paper by comparing the behavior of HPFRCC cylindrical specimens under uniaxial compression, with...

摘要:This paper describes an experimental study of the punching resistance of unbonded post-tensioned slabs with shear reinforcement. Seventeen slabs 200 mm (7.87 in.) thick and 3.0 m (9.84 ft) square were loaded at their centers and simply supported near their edges. Fifteen containe...

摘要:Experimental results gained from quasi-static cyclic tests on 34 slender structural reinforced concrete walls available in the literature are used to examine the shear deformations for displacement demands in the inelastic range. Based on these results, the distribution of shear ...

摘要:This paper deals with the analysis of reinforced concrete (RC) plane frames under monotonic and cyclic loading, including axial, bending, and shear effects. A force-based two-dimensional (2D) element based on the Timoshenko beam theory is introduced. The element formulation is ge...

摘要:It has been shown that the post-peak response of cement-based materials in compression can be defined by means of stressinelastic displacement relationships. A unique function, used to define these relationships for different cement-based materials, is introduced in the paper. Th...

摘要:This paper discusses two proof-of-concept tests conducted at 1/4 scale on a typical hollow, rectangular, reinforced concrete pier designed to support the new East Bay Skyway Structures of the San Francisco-Oakland Bay Bridge. The test units were loaded according to quasi-static, ...

摘要:Many empirical equations for predicting the modulus of elasticity as a function of compressive strength can be found in the current literature. They are obtained from experiments performed on a restricted number of concrete specimens subjected to uniaxial compression. Thus, the e...

摘要:The experimental punching capacities results of 27 punching tests on 160 to 200 mm (6.30 to 7.87 in.) deep post-tensioned slabs—all but three of them containing stud-rail shear reinforcement—are compared with resistances calculated by the methods of ACI 318 and Eurocode 2. T...
