Effective slenderness ratios for inelastic lateral buckling of throughtype arches are determined by utilizing an analogy between an arch and a column. A designer can use the effective slenderness ratio to obtain an ultimate stress for arches by substituting it into a column strength formula. The app...

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 slenderness ratio and the creep deformation of concrete. Furthermore, the direct ...
Note that for a column of a given materialσCis a function of the slenderness ratio,Le/r. Example 21.2 A tubular column has an effective length of 2.5m and is to be designed to carry a safe load of 300kN. Assuming an approximate ratio of thickness toexternal diameterof 1/16 calculate ...
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 paper an empirical formula of slip stress for verification of slipcapacity of expansive stressed grouted clamp is proposed. Theinfluence parameters on the slip stress are studied, including the contentof expansive agent, the slenderness ratio L/D, the ratio of thickness todiameter 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 (...
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...
(1) for beams, where Mu is the ultimate capacity of a beam, a, b and c are properly determined constant parameters, Mref is the reference capacity of a member without influence from sectional buckling, λs is normalized slenderness defined with the ratio between reference capacity Mref and ...
