the basic balanced axial forces, axial compressive force in the chord and in-plane bending in the chord. Finally, parametric formulae to determine the SCFs in CFST K-joints were proposed by the multiple regression analysis, and their accuracy was demonstrated through the comparison of SCFs ...

With the control parameters of the wall thickness of the ball table and the thickness of the pressure plate of the ball table, four universal wrapped assembled joint models were designed for the research of stress performance via static loading test. The
Based on the results of FE analysis, multiple regression analysis was used to obtain the SCF formulae of SHS-CFSHS X-joints under axial tension in the brace and in-plane bending in the brace. The formulae(3)–(7) are proposed for predicting the SCFs of SHS-CFSHS X-joints under axial...
It is preferable that, as to the values concerning the proof stress distribution, the following relational formula is held in the arbitrary position in the plate surface excluding prescribed regions in the ends of the steel plate: FΩ=σ<Sub>s50</Sub>-σ<Sub>m50</Sub>≥...
Experimental Study on the Stress Increment of Prestressed Tendons of Retard-Bonded Prestressed Concrete Continuous Beams Based on the bending experiment for two-span continuous beams of retard-bonded prestress concrete, the analysis of the stress increment of prestressed tend...

In the present paper, the behaviours of restraint force and bending moment and distortion in threepass welding of medium thick (12.7 mm) HT80 steel plate are investigated experimentally using H-type restrained specimens. The main results are as follows: According as the thermal contraction of weld...
Short, composite columns made from steel tubes filled with concrete were subjected to axial load plus bending moment to indicate the form of ultimate load interaction diagrams. Observations of axial load capacity and ultimate flexural capacity are discussed, together with data from laboratory tests on...
developed by a competent, licensed engineer. In lieu of a more precise structural analysis of an existing superstructure, for a steel bridge the jacking loads may be estimated from the bearing capacity of the existing girder web and bearing stiffener at the location of interest using the formula...
The design of beam-column members generally features interaction formulae, with the bending moment resistance and compressive member resistance as end points. Previous research has been carried out into the behaviour and cross-section resistance of stainless steel I-sections in bending [5–11] and ...
