GOALI: Models for R/C Structures Reinforced with Fiber Reinforced Plastics

这个GOALI项目是科罗拉多大学土木、环境和建筑工程系和加州洛斯阿尔托斯魏德林格协会应用科学分部之间的大学-行业合作项目。拟议合作的主要目的是开发一套模型，用于分析和设计使用纤维增强塑料材料加固和/或改造的钢筋混凝土结构。对于使用钢筋或垫层和夹克形式的FRP材料的结构来说，几乎不存在这样的模型。该项目旨在弥合现有的差距。将开发两个模型系列，一个用于框架的非线性静力和动力分析，另一个用于结构元素、节点和设计细节的详细分析。构成法库将补充元素开发，并将构成拟议研究的主要贡献。将提出和实施新的本构关系，适用于玻璃钢材料和由玻璃钢垫层或夹克约束的混凝土。新的定律将在实体单元和梁型单元中实施，这些单元包括在循环荷载下的剪切变形和剪切破坏的影响。

9804613This GOALI project is a university-industry cooperation between the Department of Civil, Environmental and Architectural Engineering of the University of Colorado and the Applied Sciences Division of Weidlinger Associates, Los Altos, California. The main purpose of the proposed cooperation is to develop a set of models for the analysis and design of reinforced concrete structures reinforced and/or retrofitted using Fiber Reinforced Plastic materials. Such models are almost nonexistent for structures that use FRP materials in the form of either reinforcing bars or mats and jackets. The proposed project intends to bridge the existing gap.Two families of models will be developed, one geared toward the nonlinear static and dynamic analysis of frames, the other for the detailed analysis of structural elements, joints and design details. A library ofconstitutive laws will complement the element development and will constitute a major contribution of the proposed research. New constitutive laws will be proposed and implemented for FRP materials and for concrete confined by FRP mats or jackets. The new laws will be implemented in both solid elements and beam-type elements that include the effect of shear deformations and shear failure under cyclic loads.****
