Analyses of axial compression ratio of walls in Unreinforced Masonry Structures

2011 International Conference on Electric Technology and Civil Engineering (ICETCE), 2011
Axial compression ratio of Walls in Unreinforced Masonry Structures is studied based on a 7-story concrete small block building and a 7-story common brick building with FEM. Factors that influence the axial compression ratio are analyzed. The axial compression ratio of walls in unreinforced masonry structures is compared with that of walls in concrete ...

Effect of Axial Compression Ratio on Seismic Behavior of GFRP Reinforced Concrete Columns

International Journal of Structural Stability and Dynamics, 2020
Traditional reinforced concrete columns have demonstrated poor seismic performance especially in corrosive environment as the reinforcement bars experience severe corrosion under such conditions. To overcome the problem of steel corrosion, glass fiber-reinforced polymer (GFRP) reinforced concrete columns have gained significant attention in recent ...

Experimental Study on Reinforcement Ratio of RCFT Columns under Axial Compression

Advanced Materials Research, 2011
It is clear from the former researches on reinforced concrete filled tubular steel (RCFT) structures that RCFT structures have better performance than concrete filled tubular steel (CFT) structures, in other words, because of the existence of reinforcement, the performance of RCFT differed from that of CFT.

Ratio of cube strength to axial compressive strength of rocks

Soviet Mining Science, 1978
1. For salt rocks of the Starobinsk potash salt deposit a hyperbolic relation exists between the compressive strengths and h/d, determined by the equation $$\sigma = 124.6 + \frac{{178.2}}{{h/d}},kgf/cm^2 .$$ 2. The ratio between the axial compressive strength (h/d≥2) and the cube strength (h/d=1) was as follows: for salt rock 0 ...
