Post-Tensioned Shotcrete Shearwalls

- Resumen:
By combining the advantages of conventional reinforced concrete construction with unbonded post-tensioning, a hybrid is created that provides the opportunity to significantly and cost-effectively improve the seismic performance of structural wall systems. The implementation of this hybrid wall system is illustrated using a recently completed seismic retrofit of an existing six-story non-ductile concrete building in Berkeley, CA. Various restrictions during the retrofit led to the use of shotcrete to construct the walls, micropile foundations, and carbon fiber collector elements.

Launch and Shift of the Tiziano Bridge
- Autor:

Chiara Rosignoli
- Resumen:
Construction of this twin box-girder bridge over the Tanaro River in Alessandria, Italy, not only used the innovative segmental launching method, it also included a variation in which the first box-girder was launched and then shifted to the side to make way for the second box-girder. This allowed the construction of only one set of temporary supports, decreasing the cost and shortening the construction duration for the project.

Critical Milestones in Development of Post-Tensioned Buildings
- Autor:
Bijan O. Aalami
- Resumen:
Post-tensioning was understood as early as 1860, but it was about 100 years before the first successful projects were built in the U.S. The subsequent 50 years saw rapid growth in the number of post-tensioned buildings and maturity in its construction and design technology. The performance and economical advantages of post-tensioned buildings have been recognized, and many other regions of the world are now embracing this U.S. spearheaded technology. This article reviews some of the critical milestones that have made post-tensioning the choice for many residential and commercial buildings.
