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

9804613这个GOALI项目是科罗拉多大学土木、环境和建筑工程系与加州洛斯阿尔托斯魏德林格协会应用科学部之间的一个大学-工业合作项目。 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。 这种模型对于使用FRP材料的结构几乎是不存在的，无论是钢筋或垫和护套的形式。 该项目旨在弥合现有的差距。将开发两个系列的模型，一个用于框架的非线性静态和动态分析，另一个用于结构元件、接头和设计细节的详细分析。 一个图书馆的构成法将补充元素的发展，并将构成一个主要的贡献，拟议的研究。 将提出并实施新的本构关系，用于FRP材料和FRP垫或护套限制的混凝土。 新定律将在实体单元和梁型单元中实施，包括循环载荷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.****
