Axial compression ratio limit for self‐centering precast segmental hollow piers
Structural Concrete, 2017Axial compression ratio limit was investigated for self‐centering precast segmental hollow piers based on post‐earthquake residual axial loading capacity. The analytical method of unbonded posttensioning tendons (PT) stress increment and the simplified method of compression zone height were developed and validated by the finite element model verified ...

Ductility design of RC columns. Part 1: consideration of axial compression ratio
HKIE Transactions, 2016ABSTRACTTo evaluate and quantify the effect of the axial compression ratio (ACR) on the seismic performance of reinforced concrete (RC) columns, studies of analytical relationships between the axial compression and the mechanical behaviour of RC columns were conducted, followed by a comprehensive statistical analysis with 474 sets of experimental data.

Axial Compression Ratio Limits of HSC Columns Confined with High-Strength Stirrups
Advanced Materials Research, 2010A total of 10 high-strength concrete columns confined by high-strength complex stirrups were tested under cyclic lateral force and a higher constant axial loading. The results indicate that the hysteresis loop of this type of columns still shows plump spindle-shaped at higher axial compression ratio, with better ductility, energy dissipation capability

Ratio of cube strength to axial compressive strength of rocks
Soviet Mining Science, 19781. 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 ...

Effect of axial compression ratio on concrete-filled steel tube composite shear wall
Advances in Structural Engineering, 2018This study proposes a new type of shear wall, namely, the concrete-filled steel tube composite shear wall, for high performance seismic force resisting structures. In order to study the seismic behavior of concrete-filled steel tube composite shear wall, cyclic loading tests were conducted on three full-scale specimens.
