Beam-to-beam jointEquivalent frameThis paper focuses on the stiffness and resistance of the additional plate in bending. This is a component which appears in beam-to-beam bolted steel joints, when a secondary beam with a flush end plate is attached orthogonally to the primary beam by an ...

performance control, briefly introduce the structure sensitivity knowledges, describe the establishing process of the parameterized finite element model, particularly study the sensitivity analysis results, and determine the beam and cross section properties to bending and torsion stiffness biggish influencing....
Analytical expressions for the coupled bending-torsional dynamic stiffness matrix terms of an axially loaded uniform Timoshenko beam element are derived in an exact sense by solving the governing differential equations of motion of the element. The symbolic computing package REDUCE has been used to gene...
Could anyone help me with the theory to obtain the Stress and bending moments of the beam. As I said i have been going through the Roarcks book but to no avail. Many thanks! Engineering news on Phys.org Researchers figure out optimal stiffness-toughness trade-off Research team develops me...
Biomimetic scales provide a convenient template to tailor the bending stiffness of the underlying slender substrate due to their mutual sliding after engagement. Scale stiffness can therefore directly impact the substrate behavior, opening a potential av
The rod supports a weight of 100 lb and is pinned at its end A. It is also subjected to a couple moment of 100 lb\cdot ft. The spring has an unstreched length of 2 ft and a stiffness of k=50lb/ft. Det Determ...
Most of the design codes (ACI-318-2008 and Euro Code–2-2004) propose the moment magnifier method in order to take into account the second order effect to design slender reinforced concrete columns. The accuracy of this method depends on the effective flexural stiffness of the column. This pa...
1 (a), bamboo in nature has light weight, good stiffness and structural stability, and the slenderness ratio is 1:50–1:150 [25], which can be regarded as the natural structure with the highest utilization ratio of materials. As shown in Fig. 1(b), a bamboo consists of a series of...
This paper discusses the analytical finding of the required stiffness values of the supports, which would provide the given first natural frequency of bending vibrations for a spring-hinged beam. The solution is obtained through the support coefficient, the value of which, according to the theory ...
