Load Testing of Concrete Building Structures

Castellated beams In our August column, Mr. A. Billingham posed a problem about the design of these beams in accordance with BS 449, particularly in respect of lateral buckling. Mr. A. D. Weller has responded saying: I am enclosing a copy of a letter sent to Mr. A. Billingham following his question in The Structural Engineer for August 1978. Unfortunately, the answer to his problem would require considerable research work, which may well indicate that castellated beams need restraint at close intervals. Verulam

This paper examines the reasons for, and the practical aspects of, load testing concrete structures, in particular floors and roofs, and the problems that have been encountered when testing in the field. It briefly discusses other types of structure, and comments on the recommended loadings. D.S. Jones and C.W. Oliver
