INFLUENCE OF CONSTANT AND VARIABLE PASTERNAK FOUNDATIONS ON DAMPED SIMPLY SUPPORTED BERNOULLI-EULER BEAM UNDER MOVING LOADS
Abstract: This study presents an analytical investigation of the dynamic behavior of a simply supported uniform Bernoulli-Euler beam resting on both constant and variable Pasternak foundations subjected to concentrated moving load with damping. The governing equations of motion were formulated by incorporating the effects of foundation stiffness, shear interaction, damping, and load inertia. Analytical solutions were obtained for both moving-force and moving-mass problems. For the constant foundation case, the Generalized Finite …

Effect of Nano-Fillers on the Mechanical and Fracture Behavior of Polymer Composite Matrices: A Review
Abstract: The modification of polymer composite matrices through the incorporation of nano-scale fillers has become a prominent and highly effective strategy for enhancing mechanical performance, stiffness, and fracture resistance. Unlike conventional micro-scale reinforcements, nano-fillers possess exceptionally high surface area–to–volume ratios and unique physicochemical characteristics that significantly influence interfacial phenomena within the polymer matrix. Materials, such as carbon nanotubes (CNTs), graphene nanoplatelets (GNPs), nano-silica, and layered silicate nanoclays, introduce advanced toughening mechanisms …

Review Study on re-strengthening of reinforced concrete circular column using steel strips
Abstract: This technique fixes thin steel plates i.e. steel encasement or tie plates i.e. steel cage around the column with steel angles at each corner, clamped to the concrete and welded together. Adequate tightening of the jackets can be ensured by means of heat tensioning. The use of steel jackets can enhance the shear strength of columns considerably. However, due to their low flexural stiffness they typically have poor confinement efficiency …

Prediction of Circular Frequency of Precast Concrete Piles with Distributed Mass by Resonance Moment–Displacement Approach
Abstract: This paper presents the results of circular natural frequency of single piles from critical buckling load by resonance moment-displacement approach. The support end conditions considered are pinned-pinned, fixed-fixed, and fixed-pinned respectively. It was assumed that resonance moment occurs when the bending moment diagram is made equal to zero at the supports while the resonance displacement is the sum total deflections resulting from the system reduction to an equivalent pinned-pinned system. …
