项目摘要
In the past three decades fiber-reinforced polymer (FRP) composites have emerged in structural engineering with superior characteristics for the strengthening of existing structures and the construction of new systems. The use of FRPs in short concrete columns have been extensively investigated and the outcomes have been translated into design guidelines and codes for practicing engineers. However, the performance of long (slender) concrete columns with significant lateral (second-order) deformations induced by axial compression loading and consequence buckling failure have not been investigated with required depth and breadth to establish a comprehensive data platform for the development of reliable design equations and procedures. The applicant has contributed to the field of slender columns in the past five years and is ready to take the research to the next level creating a significant advancement in the field. As Canada Research Chair (Tier 2) in Sustainable Infrastructure, the application has also acquired a state-of-the-art CFI equipment and built a unique horizontal test setup to test a variety of slender columns. The test setup can accept a broad range of slender columns (virtually up to 15 m long) and different cross-sectional geometries. In this research program, large-scale slender columns will be under out of axis (eccentric) axial compression loading. The following parameters will be considered: (1) internal and external reinforcement systems in forms of FRP bars, laminates, tubes an shells; (2) shape of cross-section including rectangular and circular sections; (3) slenderness ratio; (4) load eccentricity; (5) reinforcement ratio; and (6) FRP strength and modulus. The research program will also include a comprehensive theoretical study based on the second-order deformations considering a broad range of cross sections, boundary conditions, material properties, and FRP systems. The theoretical study will be verified against the experimental study to perform a comprehensive parametric study. The parametric study will be geared toward creation of large data platform for statistical and reliability-based analyses to propose reliable design equations and procedures to fill the gaps of current CSA design codes for manufacturers and practicing engineers. The research program will also provide a strong platform for training highly qualified personnel skilled in advanced technologies. The outcomes of the research program not only will serve to elevate Canada to a leadership position in the area of slender columns and associated advanced technologies, but also will seek innovative and sustainable solutions for the country's deteriorated infrastructure, such as bridges and water front structures with slender columns.
在过去的三十年中,纤维增强的聚合物(FRP)复合材料已经出现在结构工程中,具有较高的特征,可增强现有结构和新系统的构建。在简短的混凝土柱中使用FRP已得到广泛研究,结果已转化为设计指南和实践工程师的代码。然而,尚未使用所需的深度和广度来研究以轴向压缩负荷引起的长(细长)混凝土柱的性能,这些轴向压缩负荷引起的显着横向(二阶)变形和后果屈曲失败,以建立可靠的设计方程式和程序的全面数据平台。在过去的五年中,申请人为细长的专栏领域做出了贡献,并准备将研究提升到一个新的水平,从而在该领域创造了重大进步。作为加拿大研究主席(第2层)在可持续基础设施方面,该应用程序还购买了最先进的CFI设备,并建立了独特的水平测试设置,以测试各种细长的柱子。测试设置可以接受广泛的细长柱(实际上最多长15 m)和不同的横截面几何形状。 在该研究计划中,大规模细长的柱将在轴线(偏心)轴向压缩载荷之下。将考虑以下参数:(1)内部和外部加固系统以FRP棒,层压板,管子的壳形式; (2)横截面的形状,包括矩形和圆形截面; (3)细长比率; (4)负载偏心; (5)增强率; (6)FRP强度和模量。研究计划还将基于考虑广泛的横截面,边界条件,材料特性和FRP系统的二阶变形,包括一项全面的理论研究。理论研究将针对实验研究进行验证,以进行全面的参数研究。参数研究将旨在创建大型数据平台,用于基于统计和可靠性的分析,以提出可靠的设计方程式和程序,以填补为制造商和实践工程师的当前CSA设计代码的空白。该研究计划还将为培训高级技术的高素质人员提供强大的平台。该研究计划的结果不仅将使加拿大在细长的柱子和相关的先进技术领域提升到领导地位,而且还将为该国的基础设施不断恶化寻求创新和可持续的解决方案,例如桥梁和带有细长柱的水面结构。
