The specimens can be assigned into two groups, the first group (L60L, L75L, and L90L) with an...
Additionally, this paper provides an in-depth analysis of FUCFSTCs' mechanical behavior, failure mode, and stress process under an axial load. In conclusion, this research proposes an axial compression limit bearing capacity formula for FUCFSTCs via statistical regression, with a maximum...
Refer to Han and Frost [4] for in-depth design formulae to calculate the critical buckling load of shell–core composite piles. 4.2.2 Geotechnical vertical load behaviour Geotechnical engineers are generally more concerned with static load tests and determining the soil-pile failure load. A ...
the formula of model parameters related to steel corrosion rate are proposed and deteriorating double lines restoring force model of corroded reinforced concrete columns for axial load and moment is established.Compared with experimental results in another literature,it is founded that the restoring force...
axial load ratio to satisfy the ductility demand for seismic design of the composite columns.Finally,the limit value of the axial compression ratio is proposed on the basis of satisfying finite ductility of the composite columns(μΔ≥3)through the conversion formula between test axial compression ...
formula.The influence of intermediate principal stress on the ultimate load was studied and the failure mechanism of the column under axial compression load was discussed.The ultimate load increased with the coefficient b.The results of the proposed formula are found in good agreement with experiment...
1(a). But this value is identical with the factor for the column without corbel load and cannot fully reflect the influence of end restrain stiffness and crane height. Chinese Standard, GB 50017-2003 [6], provides a formula for effective length factors of the chord member shown in Fig. 3...
Concrete-filled steel tubular columnSize effectMeso-scale numerical methodShear failureTheoretical formulaConcrete-filled steel tubular (CFST) short columns under the action of wind and seismic load often endure high shearing force and show brittle shear failure, which may exhibit obvious size effect. ...
New formulae are also proposed for the critical load of the bar under its own weight acting alone, and under different support conditions. 展开 关键词: Theoretical or Mathematical/ Bessel functions buckling differential equations/ nonhomogeneous equation Bessel functions buckling uniform column weight ...
