An approach on the prediction of sound transmission loss for finite clamped composite sandwich plates with foam core is described in the paper. Sandwich plates are treated as being orthotropic and the apparent bending stiffness is calculated for the two principle directions. The apparent bending stiffness of sandwich plate is estimated by finite element calculation on beam elements cut from the sandwich plate.

The purpose of this work is to offer a method for detecting structural damage utilizing the standardized index of the beam's deflection influence line difference as input data for the evaluation procedure. The displacement influence line used in the evaluation is calculated using the findings of the behavior analysis of the reinforced concrete beam's finite element model when subjected to a moving load.

The pontoon-separate floating bridges have many advantages to apply to the construction of civil floating bridges in Vietnam. This article presents the study of the influence of beam stiffness on the force transmission of concentrated load to the pontoon and the bending moment in the beam caused by this load, as a basis for designing civil poonton bridge to carry loads for small tonnage motor vehicles serving rural traffic.

This paper presents a compact design of compliant mechanism that produces single degree-of-freedom (DOF) for accurate linear motion and large stroke with low input force of below 10N from the linear actuators. Based on the stiffness matrices and relationships between beam-type flexure elements, the analytical model of the entire compliant mechanism is proposed and its mechanical property is clarified.

The size dependent large displacement behavior of planar microbeams and microframes is studied in this paper using a corotational beam element. To account for the size effect, the modified couple stress theory (MCST) is employed in conjunction with Euler-Bernoulli beam theory in deriving the internal force vector and the tangent stiffness matrix of the beam element.

A unified higher-order shear deformation theory for static analysis of laminated composite beams is proposed in this paper. The theory is based on a higher-order shear deformation beam theory in which a general shear function is proposed. The characteristic equations are derived from Lagrange’s equations and then Ritz method is used to determine the stiffness matrix.

Effects of end-plate on the lateral buckling of doubly symmetrical I-section cantilever beam with free end restrained laterally are analyzed using the software COMSOL and linear shell finite elements. The torsional stiffness of the end-plate prevents the free warping of flanges and decreases the warping effective length of the cantilever beam.

A cantilever beam is a well-known structural element in engineering, which is only fixed at one end. This structure can be used to describe a manipulator, whose stiffness is large to ensure rigidity and stability of the system. A flexible cantilever beam provides a light-weight structure and high cost efficiency but generates vibration under high-speed positioning. In this paper, we aim to control the vibratory behavior of a flexible cantilever beam attached to a moving hub.

. In the pile-soil model, the lateral load is located at the pile head including both lateral force and bending moment. The single pile is considered as a beam on elastic foundation while shear beams model the soil column below the pile toe. The differential equations governing pile deflections are derived based on the energy principles and variational approaches.

This paper presents the elastic large-displacement analysis of planar steel frames with flexible connections under static loads. A corotational beam-column element is established to derive the element stiffness matrix considering the effects of axial force on bending moment (P-∆ effect), the additional axial strain caused by end rotations and the nonlinear moment – rotation relationship of beam-to-column connections.

This paper presents an experimental study for the structural performance of reinforced concrete (RC) exterior beam–column joints rehabilitated using carbon-fiber-reinforced polymer (CFRP). The present experimental program consists of testing 10 half-scale specimens divided into three groups covering three possible defects in addition to an adequately detailed control specimen. The considered defects include the absence of the transverse reinforcement within the joint core, insufficient bond length for the beam main reinforcement and inadequate spliced implanted column on the joint.
