Through a parametric study of slender RC columns, where consideration is given to the P– Δ effect and the time-dependent deformation of concrete, two regression formulas are proposed on the basis of the slend
Slenderness Ratio The term "L/r" is known as the slenderness ratio.Lis the length of the column andris theradiation of gyrationfor the column. higher slenderness ratio - lower critical stress to cause buckling lower slenderness ratio - higher critical stress to cause buckling ...
In this paper an empirical formula of slip stress for verification of slip capacity of expansive stressed grouted clamp is proposed. The influence parameters on the slip stress are studied, including the content of expansive agent, the slenderness ratio L/D, the ratio of thickness to diameter of...
Its derivation relies on the assumptions that linear elasticity applies to this problem, and that the slenderness ( B / L ) is an infinitesimal quantity. Here we ask the following question: What is the first non-linear correction in the right hand-side of this equation when terms up to (...
The THOR formula is widely used in the investigation of vulnerability and effectiveness of weapon system, however, its application was limited by the small slenderness ratio and limited materials of target. In order to investigate the damage effect of KE-rod warhead, this paper, basing on the ...

In this range, the maximum load is represented as a function of the compression rate, slenderness ratio, and imperfection/initial deflection. We answer the following question: 'How slowly should the column be compressed in order to measure static load-bearing capacity?' This question is important...
