Introducing the paper, Mr. Needham said that a testing rig had been evolved capable of taking beams up to 25 ft span and 2 ft 6 in. deep with two 20-ton loads, hydraulically applied at the quarter-points. It had been intended for testing a wide range of prestressed girder designs. The loads needed to impart a load factor of two, on a quarter-scale model of the girder tested at MEXE, amounted to approximately 7 tons per jack; thus the capacity of the rig would enable much stronger models to be tested.

Wind Tunnel Model Tests of a High Building of Unusual Shape

Wind Tunnel Model Tests of a High Building of Unusual Shape

The problems of wind loads on high buildings of unconventional shape are discussed as a function of building shape and characteristics of the natural wind. The new Toronto City Hall is used to demonstrate how wind loads, their distribution and fluctuation can create critical structural problems. The natural wind loads were obtained from wind tunnel tests on a City Hall model. These tests are described in enough detail to familiarize the structural engineer with the value and potential as well as the shortcomings of wind tunnel testing of buildings. G.K. Korbacher and N. Seethaler

Verulam (readers' letters - January 2016)

Letters this month raise concerns about the the forces cited in an article published in May 2015 on assessing the capacity of the Grand Parade stone balustrade in Bath, UK; as well as considering structural safety margins and code discrepancies in relation to steel web buckling.
