A Study on Effective Strains in Different FRP Shear Strengthening Schemes for Analytical Optimized Truss Models
—
by
This paper presents an optimized truss model based on the principle of minimum total energy theorem. Six most recent effective strain ɛfrp,e models including three design guidelines were selected for the analysis. Three reinforced concrete beams strengthened with different fiber reinforced polymer (FRP) schemes were chosen. Comparing with current design guidelines, the results of these…

Experimental investigation of deflected mode of the reinforced concrete beams with organized cracks under long-term loading
—
by
The experiments confirmed the hypothesis about the beams rigidity with pre-organized cracks in comparison with stochastic cracks under the influence of long-term loading. As a result, the beams with pre-organized cracks provide the smaller deflection after long-term period than the beams without organized cracks. Thus, the proposed method of the deflections calculation of the reinforced…
