摘要

本文首次尝试采用透水法和渗透法对大蓬仙人掌(Euphorbia tortilis cactus, ETC)混凝土的透水性进行了研究。在此基础上，进行了AFRP kelvar 149包覆ETC RC梁的抗弯强度两点荷载试验。本研究旨在开发一种在静载下更耐用、弯曲和可持续的梁。基于现有文献的最新信息，我们将3层Kelvar 149 AFRP作为层压板来解决ETC梁的挠度问题。在本工程中，碾压混凝土梁采用ETC和芳纶FRP板进行加固。对不同层数和图案的芳纶玻璃钢片材进行了研究。经调查，三层Kelvar 149梁的性能优于普通混凝土梁。由于文献中没有关于AFRP层压板梁的水力传导率和干燥收缩率的结果，因此在静载条件下，用有限元法(ABAQUS)对所得结果进行了验证。

Mechanical performance of ETC RC beam with U-framed AFRP laminates under a static load condition

In the presented paper, an attempt has been made to first find the permeability of the Euphorbia tortilis cactus (ETC) concrete by the water permeability method and infiltration method. After that, the flexural strength of the ETC RC beam wrapped with AFRP kelvar 149 is carried out by a 2-point load test. This research aimed to develop a more durable, flexural, and sustainable beam under static load. Based on the state-of-the-art information available in the literature, 3-layer Kelvar 149 AFRP is considered as a laminate to solve the deflections of the ETC beam. In this project, RCC beams were strengthened by ETC and aramid FRP sheets. Novel results are obtained by different layers and patterns of Aramid FRP sheets. Based on the investigation 3-layers Kelvar 149 perform well than a normal concrete beam. As no result based on hydraulic conductivity and drying shrinkage of a beam with AFRP laminates are available in the literature, the obtained results are validated with the finite element method (ABAQUS) under static load conditions.

期刊介绍： The Journal of Construction is aimed at professionals, constructors, academics, researchers, companies, architects, engineers, and anyone who wishes to expand and update their knowledge about construction. We therefore invite all researchers, academics, and professionals to send their contributions for assessment and possible publication in this journal. The publications are free of publication charges. OBJECTIVES The objectives of the Journal of Construction are: 1. To disseminate new knowledge in all areas related to construction (Building, Civil Works, Materials, Business, Education, etc.). 2. To provide professionals in the area with material for discussion to refresh and update their knowledge. 3. To disseminate new applied technologies in construction nationally and internationally. 4. To provide national and foreign academics with an internationally endorsed medium in which to share their knowledge and debate the topics raised.
