Mr J. M. Martin (Momson Construction Ltd.): I would like to comment on a number of aspects of the construction of the bridge and to discuss the means by which the deflection restraints were met.
The moment-transmitting, welded endplate connection has grown in popularity to the point where it is now believed to be the most widely used beam-to-column connection in building structures. Full utilisation of these connections depenh on a knowledge of behaviour at both ultimate and service loads. The paper attempts to establish the necessary joint characteristics using finite-element-based theoretical modelling. The theoretical results are compared with experimental observations and a limit state design method for flush endplate connections is proposed. The design data presented use a recommended standardisation of details for 'flush' and ‘extended’ endplates. W.M. Jenkins, C.S. Tong and A.T. Prescott
Claiming to be one of the increasing number of members concerned with differing philosophies, standards, and practices, I single out safety of buildings, sturdiness of construction, and design freedom, for consideration. I relate all three to the public duty role which falls on the shoulders of the profession, i.e. to protect and look after the interests of the public in matters relating to structural engineering and, at the same time, those of the profession insofar as they affect those duties. My particular concern is that those three are now being adversely affected by the differing standards, etc., and that remedial measures are needed to arrest the tendency towards decline. I encourage the Institution to set up a review committee and, if necessary, to formulate a purposeful policy to encourage members to exert the maximum influence, whenever and wherever possible, in all matters relating to our structural guardian duties to the public. S.T. Lawrence
For the Anniversary Year 1983-84 Council decided to modernise and upgrade by redecoration and refurnishing of the entrance hall and staircase and the main meeting room on the first floor. This has transformed the impression the building makes on members and visitors and is a visible celebration of the place the Institution holds in the UK and overseas. It is the public face of the Institution.
Loads on roofs Imposed loadings on roofs is a popular topic in our column, bringing some queries from Mr C. J. Cox in January on exactly what is included in the 0.75 kN/m2 imposed loading on roofs required according to BS 6399: Part 1 : 1984. Mr C. J. Judge, of the Building Research Establishment, has now written offering us an explanation. Verulam
