Calculation of flexural strength of a unitized post-tensioned concrete masonry wall system
Abstract
Bolt-A-Blok system is a unitized, post-tensioned, structural system comprised of concrete blocks, tensioned steel bolts, and bars, eliminating the need for traditional mortar. This thesis presents a refined procedure to calculate the flexural capacity of the Blot-A-Blok wall system based on results of construction tests. The objective is to develop an analysis procedure to determine strain in the bolts, and as a result, the stress in bolts at failure. Flexural capacities computed using the assumptions of bonded connections are compared with test results and with strength calculations performed by a researcher at Pennsylvania State University. Applications of the proposed method include design of residential basement walls and other simply supported walls, such as those used in "big-box" stores.
