Slender concrete walls incorporated into tilt-up construction over the past 60 years have performed remarkably well under out-of-plane wind and seismic loads. While issues associated with seismic wall anchorage gave this form of construction a black-eye in the early days, the concrete walls themselves have always performed very well even as far back as their first use in the early 1900s. Yet th...

Repairing deteriorated concrete bridge piers using externally wrapped FRP (fiber reinforced polymer) composites has been proven as an effective approach. This technique has also been applied to low-rise building structures. Failures in FRP-wrapped concrete structures may occur by flexural failures of critical sections or by debonding of FRP plate from the concrete substrate. Debonding in the FR...

This paper first analyzes the tilting reasons of a steel-concrete building in Zhangjiakou city in China. Then, a jacking rectification method which combines the pie-cutting method and the excavation of stress release trench was put forward. This analysis method uses the three-dimensional numerical simulation for soil settlement and vertical displacement and internal force of upper structure in ...
