CAREER: Assessment, Maintenance, Repair, and Rehabilitation of Historic Structures

布斯：这是一个职业奖。该项目将为历史建筑开发新的修复技术，并将开展教育活动，培养对历史建筑、结构和土木工程的尊重，以及对其维护、修复和修复的兴趣。教学和研究活动将采用多学科的视角，包括建筑史、建筑史、建筑学、土木/结构工程和景观建筑的投入。要研究的修复技术涉及到新型复合纤维增强塑料（FRP）材料的应用，它们在历史建筑上的应用被认为是FRP材料在混凝土、钢和砖石结构修复中更广泛使用的一个苛刻的试验台。研究的具体结构类型包括砌体和混凝土拱桥、金属桁架桥、20世纪中期的板梁和板桥、无筋承重砌体建筑和薄壳钢筋混凝土结构。这些建筑类型需要解决的具体问题包括填充拱桥的横向效应、桁架桥的荷载分布和楼板系统问题、东部地区中等地震中URM建筑的护墙和飞檐的危害、薄壳混凝土结构的环境破坏。要研究的修复技术包括用玻璃钢材料替换关键元件，外部粘合玻璃钢片加固，外部非粘合玻璃钢加固（绑带），以及使用玻璃钢修复材料的化学和机械预应力。＊＊＊

9624614 Boothy This is a CAREER Award. The project will develop new repair techniques for historic structures and will develop educational activities that will cultivate a respect for historic buildings, structures, and civil works, and an interest in their maintenance, repair, and rehabilitation. The teaching and research activities will adopt a multidisciplinary perspective, including architectural history, architectural history, architecture, civil/structural engineering, and landscape architectural input. The repair techniques to be studies involve the application of new composite Fiber Reinforced Plastic (FRP) materials, and their application to historic structures is considered a demanding test bed for the more general use of FRP materials in the repair of concrete, steel, and masonry structures. The specific types of structures to be included in the study are masonry and concrete arch bridges, metal truss bridges, mid-20th century slab girder and slab bridges, unreinforced load bearing masonry buildings, and thin-shell reinforced concrete structures. The specific issue to be addressed for these building types include transverse effects in filled arch bridges, load distribution and floor system issues in truss bridges, the hazard of parapets and cornices of URM buildings in Eastern locations in moderate earthquakes, environmental damage to thin-shell concrete structures. The repair techniques to be studied include replacement of critical elements with FRP materials, externally bonded FRP sheet reinforcement, external unbonded FRP reinforcement (banding), and chemical and mechanical prestressing using FRP repair materials. ***
