Glass fiber-reinforced polymer (GFRP) bars constitute a feasible alternative to steel in reinforced concrete (RC) structures in areas where environmental conditions may be adverse to steel reinforcement. Use of GFRP in other areas, however, has been limited due to the reduced capacity of GFRP to dissipate energy and provide ductility to structural systems. BP Composites, LTD. is a developer and manufacturer of GFRP reinforcing bars interested in expanding the applications of their product in areas with low-to-moderate seismicity or in structures that require significant energy dissipation (impact or vibration), in which currently GFRP reinforcement is not considered a feasible option. This study will show that innovative, hybrid GFRP/steel reinforced shear walls exhibit satisfactory desirable traits of conventional steel-reinforced walls such as acceptable energy dissipation and ductility, while at the same time exhibiting desirable advantages of using GFRP material. BP Composites will benefit from the analytical evidence generated in this study showing the advantages of hybrid GFRP/steel walls by allowing the company to include this type of innovative construction in its project/product portfolio.

玻璃纤维增强聚合物（GFRP）筋构成了钢筋混凝土中钢筋的可行替代品 (RC)环境条件可能不利于钢筋加固的区域内的结构。使用GFRP 然而，在其他领域，由于GFRP耗散能量和提供 结构系统的延展性。BP Composites，Ltd.是一家开发和制造GFRP增强材料的公司 酒吧有兴趣扩大其产品在低至中等地震活动的地区或 需要大量能量耗散（冲击或振动）的结构，其中目前GFRP 加强被认为不是一个可行的选择。这项研究将表明，创新的混合玻璃钢/钢， 钢筋剪力墙表现出传统钢筋混凝土墙令人满意的理想特性， 可接受的能量耗散和延展性，同时表现出使用 玻璃钢材料。BP复合材料将受益于本研究中产生的分析证据， 混合玻璃纤维增强塑料/钢墙的优点，允许公司包括这种类型的创新建设 项目/产品组合。
