The Use of Resin Injection to Repair an Impact-Damaged Motorway Bridge

Safety in design Mr Rolfe's answer to his own question ‘a man has injured his right leg and uses a walking stick. In which hand should he hold it for maximum relief?’ (Vo1.73 No. 10 May 1995) is, based on experience of a broken leg: He holds the stick in the right hand when standing and in the left hand when walking. When standing, this enables him, if necessary, to take all the load off the injured leg. When walking, the good (left) leg is necessarily clear of the ground half the time. By holding the stick in the left hand in contact with the ground during this time the total load is shared with the bad leg. Trying to do this with the right hand will merely throw him off balance. If the injured leg cannot take approximately half the total load he will have to use crutches. Verulam

The planned move of the British Library to its new location at St Pancras gave an opportunity to resolve a long-standing problem at the British Museum. The floor over the King’s Library, constructed in the 1820s by Robert Smirke incorporates longspan hogbacked iron castings made by John Rastrick. The strength and soundness of Rastrick’s girders have been the subject of much debate over the years, and the permitted imposed load on the floor has been severely restricted. The Museum was keen to apply higher loads, and this paper describes the historical background, the investigative work, and the appraisal of the existing structure, together with the design solution adopted.
