“…The high-strength and self-compacting properties of HSC could lead to significantly smaller cross-section for structural members, reduce concrete shrinkage cracks, and the construction was convenient compared to conventional concrete (Gökçe et al, 2018). To further improve the ductility of HSC, researchers have studied FRP confined concrete, which consists of FRP jackets wrapped around the outside of the concrete column (Hodhod et al, 2005; Vincent and Ozbakkaloglu, 2013; Zohrevand and Mirmiran, 2013; Yu et al, 2014; Nguyen and Choi, 2019; Ju et al, 2020). The test results show that FRP jackets would increase the ductility, ultimate strength, and elongation of HSC columns by up to 300%, 198%, and 195%, respectively.…”

To solve the instability of the compression bars in the space truss composed of GFRP tubes, a composite column with high-strength concrete (HSC) confined by glass fiber-reinforced plastic (GFRP) tube was proposed. High-strength self-compacting micro-expansive concrete with a slump greater than 255 mm was produced under normal-temperature curing conditions and confined by GFRP tubes. A mechanical performance test of the GFRP-confined HSC short column under axial compression was performed. The effects of GFRP tube types, concrete expansion agent, constraint effect, ultimate load capacity, and failure mode of the composite structure were discussed and analyzed through the test. A model of the stress-strain response of the GFRP confined HSC column was proposed. The results show that the 45° fiber-wound GFRP tube has a significant restraining effect on the HSC. The stress-strain relationship increases quadratically in a linear fashion. When the composite column was damaged, the GFRP fiber was broken and the concrete was crushed. The ultimate strength was about 1.5 times that of unconstrained HSC columns, and the loading method has less influence on the results. The expansion agent has a significant effect on the deformation performance of the composite column, and its ultimate strain was about 1.4 times that of the composite column without expansion agent.

“…Natural disasters occur worldwide and, among them, earthquakes are considered the most destructive as they leave severe social and economic impacts. Civil structures could be collapsed when an earthquake occurs if the structures are not adequately designed for the level of the earthquake [1][2][3]. The collapsed of the structures could not only injure people but also require a high cost of damaged structures demolition [4].…”

Response modification factor (R) is a significant design parameter of steel structures under seismic loads. Thus, determine the factor benefits the design process. This study aims to evaluate the values of response modification factors of multiple story steel buildings with considering various damping ratios. Different types of steel structures, from 4-to 12-story buildings, with various damping ratios were first analyzed using SAP software. The results from SAP, then, have been used to calculate the response modification factors using existing models. Results indicate that the use of damper increases significantly the response modification factors of steel structures, e.g., the factor of structures with dampers are 22 -110% higher than the structures without dampers. The height of structures and the number of viscous dampers was found to have significant effect on the response modification factor.

Starch nanoparticles, synthesized from native starch through the hydrolysis approach, are considered as potential reinforcers to sustainable biodegradable nanocomposite with poly(lactic)acid. Some properties of nanocomposites are upgraded to expand their applications compared to poly(lactic) acid. As relevant, starch nanoparticles are spherically shaped with mainly distributive sizes under 80 nm. Especially, they are homogeneously dispersed in the matrix polymer at high content, resulting in improving the interfaces between matrix polymer and starch nanoparticles, thermal stability, and mechanical properties of nanocomposites.
