Study on Axial Compressive Behaviors and Bearing Capacity Formulas of the Composite CFST Columns

The Effectiveness of Deep Soil Mixing on Enhanced Bearing Capacity and Reduction of Settlement on Loose Sandy Soils

A large portion of Iran railway routes are located in sandy desert areas. Therefore, paying attention to soil stabilization methods seems essential. In present study, in parallel to introducing the deep soil mixing as an efficient and economic method of soil improvement, in the frame work of a practical example, assuming loose sandy soil parameters, feasibility of the method application is inve...

investigation of the stability and vibration of cracked columns under compressive axial load

in this paper, a new analytical method is proposed to study the effect of crack and axial load on vibration behavior and stability of the cracked columns. using the local flexibility model, the crack has been simulated by a torsional spring with connecting two segments of column in crack location. by solving governing eigenvalue equation, the effect of crack parameters and axial load on the nat...

Analytical Load Displacement Curves of RC Columns under Constant Axial and Cyclic Lateral Loads

The cyclic tests of the columns are of practical relevance to the performance of compression members during earthquake loading. The strength, ductility and energy absorption capabilities of RC columns, subjected to cyclic loading, have been estimated by many researchers. These characteristics are not normally inherent in plain concrete but can be achieved by effectively confining columns throug...

Reduction of load-bearing capacity of all-ceramic crowns due to cement aging.

The purpose of this study was to investigate how water aging of the resin cement influences the stress distribution in all-ceramic crowns and if there is an increase in the propensity for crown failure. The failure of all-ceramic crowns attributed to cement degradation was explored using a combination of experimental and numerical methods. Sectioned all-ceramic crown specimens were fabricated o...
