Prediction formulaePrevious studies have showed that severe earthquake could cause damage to concrete filled steel tube (CFST) column. Although the energy dissipator can be used to improve the seismic performance of the CFST column, its enhancement is limited. Based on a new passive control ...
Influence of end plate splices on the load carrying capacity of columns A column splice is part of the column and therefore must be designed for second order bending moments and shear forces in addition to the axial force. In t... HH Snijder,JCD Hoenderkamp - 《Journal of Constructional ...
Total 14 CFT short and long column specimens were tested under the axial compression. Test results were analyzed in the viewpoint of axial load capacity, load-shortening relationship, and failure aspect. KBC 2016 code was used to evaluate the test results. The results of this study were as ...
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 ...
This paper studies the dynamic column buckling of multi-walled carbon nanotubes (MWNTs) under axial impact load. The analysis is based on the continuum mec... C Sun,K Liu - 《Solid State Communications》 被引量: 9发表: 2009年 Limitations of current design procedures for steel members in sp...
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...
2) equivalent axial compression load 等效轴心受压荷载 1. Presented in this paper is a simple and quick method of designing beam-column channel sections by introducing equivalent axial compression load. 采用等效轴心受压荷载,按轴心受压构件设计承受轴力和弯曲荷载的槽形截面 双肢柱及单肢柱,使得槽形...
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...
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. ...
According to the results, the load capacity of the composite columns increased with increasing concrete strength and decreased with increasing length/diameter ratio. In general, the code provisions were highly accurate in the prediction of column capacity. Among them, the Brazilian Code was the most...
