The research objective of this Faculty Early Career Development (CAREER) project is to close the knowledge gaps about the behavior of cold-formed steel lateral force resisting systems that use shear walls sheathed with steel or wood panels. The study includes three major tasks: 1) Configuring a unique testing method designed to investigate the performance of cold-formed steel shear walls under realistic loading conditions to provide reliable experimental data to evaluate the current code prescribed shear wall strengths. 2) Based on the experimental data, establish accurate analytical models to predict the shear strength of cold-formed steel shear walls made with different sheathing materials and to provide design equations based on the principles of mechanics and mathematical models. 3) Develop advanced designs of high-performance shear wall systems with enhanced ductility and strength for low cost building constructions in seismic and strong wind zones. The results of this research will provide simplified and improved methodologies for safe and more economical design of building structures using the cold-formed steel shear walls which are known to be recyclable and provide better fire resistance compared to wood construction. This research will also make it feasible to use the cold-formed steel walls in taller buildings than what has been possible now in seismic and high wind regions. The educational activities of the project with the developments of hands-on experiments and teaching aids and a comprehensive text book will lead to improvements in teaching about the cold-formed steel structures to both graduate and undergraduate students. This will also promote professional interest in the use of this economical and sustainable method of building construction. Graduate students will receive advanced training in research methods through their direct involvement in the project research. The research results will be disseminated through publications in professional journals and conference proceeding as well as through a project website.

这个教师早期职业发展（职业）项目的研究目标是弥合有关使用钢或木板护套的剪切墙的冷形成钢横向力系统行为的知识差距。该研究包括三个主要任务：1）配置一种独特的测试方法，旨在调查在逼真的加载条件下冷形成钢剪墙的性能，以提供可靠的实验数据，以评估当前规定的规定剪切壁强度。 2）基于实验数据，建立准确的分析模型，以预测用不同护套材料制成的冷形成钢剪切壁的剪切强度，并根据力学和数学模型的原理提供设计方程。 3）开发高性能剪力壁系统的先进设计，具有增强的延展性和强度，可在地震和强风区中低成本建筑。这项研究的结果将提供简化和改进的方法，以使用冷形式的钢剪墙为建筑结构提供安全，更经济的设计，与木材结构相比，该钢制剪切壁可回收可回收并提供更好的火力阻力。 这项研究还可以使在高建筑物中使用冷形成的钢壁比现在的地震和大风区域可行。通过动手实验和教学辅助工具以及全面的教科书的发展，该项目的教育活动将改善有关研究生和本科生的冷形式钢结构的教学。 这还将促进对这种经济和可持续建筑建设方法的使用的专业兴趣。 研究生将通过直接参与项目研究来接受研究方法的高级培训。研究结果将通过专业期刊和会议程序以及项目网站的出版物进行传播。
