Achievements of Truss Models for Reinforced Concrete

Achievements are presented for truss models of RC structures developed in previous years: 1. Two constitutive models, biaxial and triaxial, are based on regular trusses, with bars obeying nonlinear uniaxial σ-ε laws of material under simulation; both models have been compared with test results and show a dependence of Poisson ratio on curvature of σ-ε law.

Behavior and Design of High-Performance Fiber-Reinforced

Abstract: A series of tests has been conducted to investigate the use of strain-hardening, high-performance fiber-reinforced concrete (HPFRC) in the critical regions of coupled-wall systems. A component test phase, consisting of tests of three large-scale precast coupling beam specimens with span-to-depth ratios (l_n⁄h) of 1.75 subjected to reversed cyclic loading, was conducted to evaluate

Performance of Retrofitted Square Reinforced Concrete

In this study, testing of 3 square column samples of reinforced concrete with dimensions of 300 300 mm. The first specimen is fully retrofit on the entire cross-section of the column, the second specimen is retrofitted on the plastic hinge area of the column and the third specimen is a control column without retrofit.
