Stiffness constant and effective mass are two important parameters in the performance analysis of an accelerometer. Their values depend mostly on the structural design of the comb finger-type accelerometer, especially its suspension beam design. In this study, the formulation of the stiffness constant ...
After an extensive study of the relevant entities the above principle is successfully applied to the derivation of the geometrical stiffness of a beam element in space. The consistency of the present approach is demonstrated by the full agreement with the prior results of the authors based on the...
General variational principles and two-sided estimates for a nonhomogeneous beam of periodic structure are derived on the basis of the asymptotic method and analysis of Lagrange and Castigliano functionals for the so-called cell problem. The nonhomogeneity of the beam can be a result of non...

Matrix Structural Analysis" by J.S. Przemieniecki, pp 388-391, McGraw-Hill, 1968. His derivation is for a 2D beam (6 DOF), but is easily extended to 3D (12 DOF). I've successfully used this to determine beam buckling as well as the effect of end-loading on the lateral ...
The flexible crashworthy structure can significantly mitigate the ship impact force on bridge pile.This paper establishes an analytical model to obtain the equivalent elastic stiffness of the structure.The model is composed of a closed circular beam connected to the circular foundation with distributed ...
A lightweight, high-stiffness structural beam having a web and a chord, which features a cross-sectional geometry featuring a plurality of sides arranged in an asymmetrical, non-closed, convex polygon shape. At least three of the sides of the chord are substantially parallel to one another, an...
Christoph Hahn, technical education specialist at MathWorks, introduces you to an efficient approach to determine structural properties of a steel tube frame using the direct stiffness method. Determining the structural properties of a truss or beam framework is part of many introductory mechanics ...
Objective: The moment-curvature curves of all tested beams are obtained based on the experimental study. The change characteristics of flexural stiffness for tested beams are analyzed, and the short-term flexural stiffness formula is derived. Results: Finally the computed values of midspan deflection ...
SummaryThe lateral stiffness and strength required of supporting beams and exterior panels of continuous reinforced concrete slab-and-beam floors in order to ensure membrane action in the panels at ultimate load is considered. It is shown that tie reinforcement may be required in the supporting beams...
