In connection with the drafting of the Code of Practice to succeed BS 449, two distinct problems were revealed relating to bolt strengths. The current values for 8.8 bolts in direct tension appeared disproportionately low having regard to ultimate tensile strength (UTS) values, compared to general grade high strength friction grip (HSFG) bolts. Also, no guidance is currently given on the ultimate shear values of general grade HSFG bolts,. although the use of a load factor of 1.4 against slip must imply that such bolts possess further capacity after slipping into bearing. M.H.R. Godley and F.H. Needham

An Assessment of High Aluminia Cement Concrete in the Superstructures of Existing Buildings. Report

Nearly 7 years have elapsed since the publication, in 1975, of the BRAC Sub-Committee P's report on high alumina cement concrete, and the Institution is concerned that many properties containing HACC that have been appraised by an engineer and found safe and adequate for purpose are still being valued lower than similar ones with OPCC. A working Party has considered the problem and has produced the assessment below.

Colloquium: Glass as a Structural Material. The Structural Properties of Glass and its Application i

This paper discusses the basic material properties that rnust be considered by the designer when producing glass structures. Various applications of these design considerations are described, together with the philosophy behind the development of particular structures. J.D. McCann

Preposed Demountable Squash Courts with Glass Walls

Preposed Demountable Squash Courts with Glass Walls

A brief history is given of spectator facilities for the game of squash and related sports, culminating in the proposed ‘all glass’ demountable courts for use in suitable indoor spectator arenas. Design constraints and two alternative preferred structural forms for such courts are described, one utilising the glass walls as the only vertical loadbearing elements to support a court ceiling. The theoretical arrd load testing justification of these structures is considered, together with some proposed constructional details. Plastic is assessed as an alternative material to glass, Some other uses for related loadbearing glass structures are suggested. G.R. Hill
