Model-Based Vibration Diagnostic of Cracked Beams in the Time Domain
… model for the transverse vibrations of beams consisting of partial differential equations of motion with varying coefficients to account for the presence of damage. In order to provide accurate representation of the structure's behavior over a broader frequency range, a new continuous …

Analysis by Meshless Local Petrov-Galerkin Method of Material Discontinuities, Pull-in Instability in MEMS, Vibrations of Cracked Beams, and Finite Deformations of Rubberlike Materials
… and forced vibrations of a segmented bar and a cracked beam, pull-in instability of an electrostatically actuated microbeam, and plane strain deformations of incompressible hyperelastic materials. The Moving Least Squares (MLS) approximation is used to generate basis functions for the trial …

Low-Shrinkage Fiber-Reinforced Concrete for Infrastructure Construction and Rehabilitation
… on bond strength and structural properties of beams was evaluated. Test results indicated that optimal SRA-MSF system led to low drying shrinkage without mitigating mechanical properties of FR-SWC. Using 1.25% SRA improved shrinkage resistance and flexural post-cracking behavior. Adding 0.66% …

Strengthening prestressed beams using parafil ropes as external tendons
… efficient anchorage system. Thirteen prestressed beams,one with internal prestressing steel only, and the rest strengthened externally using Parafil Ropes Type G were tested up to failure under two third point loading. Six factors were studied to investigate their effect on the behaviour of …

Experimental assessment of cracked steel beams under mechanical loading and elevated temperatures
… been conducted to evaluate the response of steel beams under elevated temperature. However, to date, there is lack of information on the response of steel beams with pre-existing cracks under elevated temperature. The importance of evaluating cracked steel beams under elevated temperature stems …

Quantification of bond strength between cementitious materials and microbially-induced calcium carbonate precipitates
… damaged, and treated Portland cement mortar beams. Sporosarcina pasteurii in nutrient media was applied to cracked beams in two different environmental conditions. Several experimental control treatments lacking bacteria were applied to additional sets of beams. Furthermore, bio-deposits were …
