Journal of Research Updates in Polymer Science https://mail.lifescienceglobal.com/pms/index.php/jrups <p>This journal aims to bring together participants from academia and industry in highlighting the advances in polymer research along with its application to global development. The journal seeks to promote and disseminate knowledge of the various topics and technologies of Polymer research in various sectors like industry, agriculture, health, water, shelter and environmental management. The journal will disseminate the research results among development policymakers, scholars and practitioners with a hope to identify new research directions. It can also have practical implications within interdisciplinary developing fields such as functional / specialty polymers, biomaterials, drug delivery, electronic applications, composites, conducting polymers, liquid crystalline materials; and bring contribution in new fabrication techniques.</p> en-US <h4>Policy for Journals/Articles with Open Access</h4> <p>Authors who publish with this journal agree to the following terms:</p> <ul> <li>Authors retain copyright and grant the journal right of first publication with the work simultaneously licensed under a <a href="http://creativecommons.org/licenses/by/3.0/" target="_new">Creative Commons Attribution License</a> that allows others to share the work with an acknowledgement of the work's authorship and initial publication in this journal.<br /><br /></li> <li>Authors are permitted and encouraged to post links to their work online (e.g., in institutional repositories or on their website) prior to and during the submission process, as it can lead to productive exchanges, as well as earlier and greater citation of published work</li> </ul> <h4>Policy for Journals / Manuscript with Paid Access</h4> <p>Authors who publish with this journal agree to the following terms:</p> <ul> <li>Publisher retain copyright .<br /><br /></li> <li>Authors are permitted and encouraged to post links to their work online (e.g., in institutional repositories or on their website) prior to and during the submission process, as it can lead to productive exchanges, as well as earlier and greater citation of published work .</li> </ul> support@lifescienceglobal.com (Support Manager) support@lifescienceglobal.com (Technical Support Staff) Mon, 19 Jan 2026 10:20:18 +0000 OJS 3.3.0.10 http://blogs.law.harvard.edu/tech/rss 60 Shear Strengthening of Deep Beams Using Polymer-Based CFRP Bars via the Near-Surface Mounting (NSM) Technique https://mail.lifescienceglobal.com/pms/index.php/jrups/article/view/10796 <p class="04-abstract">Near-surface-mounted strengthening with polymer-based carbon fiber-reinforced polymer (CFRP) bars has been proved as one of the efficient techniques in enhancing the shear capacity of reinforced concrete RC deep beams. This paper presents an experimental investigation on the shear behavior of RC deep beams strengthened with NSM CFRP bars. Five identical RC deep beam specimens with the same geometry and internal steel reinforcement were tested under two-point loading. One specimen was left un-strengthened as a control beam; while four specimens have been strengthened by CFRP bars embedded in the shear zone with two orientations, 0°/90° and 45°/135°, and two spacing configurations, 100 and 150 mm. Response parameters of prime interest included first shear cracking load, ultimate shear capacity, crack pattern, and mid-span deflection. The findings of the experiment demonstrated that NSM CFRP strengthening improved the shear performance of deep beams; depending on the orientation and spacing of the CFRP bars, shear capacity augmentation ranged from about 14% to 47% in comparison to the control specimen. Additionally, at similar load levels, strengthened beams demonstrated a 10% to 40% decrease in mid-span deflections and fracture widths. The test results demonstrate how well polymer-based CFRP bars inserted using the NSM technology improve the stiffness and shear strength of RC deep beams.</p> Alyaa Abdulrazzaq Azeez Copyright (c) 2026 https://creativecommons.org/licenses/by-nc/4.0 https://mail.lifescienceglobal.com/pms/index.php/jrups/article/view/10796 Mon, 19 Jan 2026 00:00:00 +0000 Structural behavior and Thermal Stress Response of Steel Members under Thermo-Environmental Loading for Polymer Reinforced Structural Systems https://mail.lifescienceglobal.com/pms/index.php/jrups/article/view/10797 <p>The structural behavior and thermally induced stresses of steel members play an important role in the safety, serviceability and long-term performance of civil engineering structures exposed to high temperatures and high humidity. Variations in stiffness, thermal deformation and stress redistribution directly affect the bearing capacity, deflection limit and durability of structural components, especially when polymer-based coatings and hybrid polymer-metal systems are used for environmental protection. In this study, a numerical investigation is performed to measure the thermomechanical response of commonly used structural steels (AISI 304, 316, 1020 and 1045) subjected to coupled thermal and humid conditions. Key structural parameters including elastic stiffness degradation, thermal deflection and thermal stress development are evaluated to support rational material selection and performance-based structural design. The results show that increasing temperature gives a significant increase in deflection for all steel grades due to a reduction in Young's modulus, while the thermally induced stress decreases as a result of hardness softening. Carbon steels (1020 and 1045) exhibit low thermal deflection and high structural stiffness, while stainless steels (304 and 316) exhibit superior resistance to moisture-induced corrosion and environmental degradation, which is essential for durability-oriented structural applications. These findings highlight the inherent trade-off between structural stiffness, thermal compatibility and environmental resistance when choosing a steel substrate.</p> Kamal Ali Mohammed, Thaer Matlab Mezher Copyright (c) 2026 https://creativecommons.org/licenses/by-nc/4.0 https://mail.lifescienceglobal.com/pms/index.php/jrups/article/view/10797 Mon, 19 Jan 2026 00:00:00 +0000
