BS 8490:2007 Guide to siphonic roof drainage systems
BS 8490:2007 Guide to siphonic roof drainage systems
BS 8490 is the British Standard applies to roof drainage systems using circular-section pipes that operate under siphonic action. It does not apply to siphonic drainage systems using rectangular or trapezoidal section conduits for water conveyance.
It gives information and provides guidance on design parameters, installation, verification and maintenance needs of siphonic roof drainage systems. Guidance is also given on carrying out checks of designs, for the use of specifiers and regulatory authorities. Particular issues for site drainage systems that receive flows from siphonic roof drainage systems are also covered.
BS 8490 should be read in conjunction with BS EN 12056-3 which deals with the layout and calculation of roof drainage. BS8490 gives information facilitating the use of BS EN 12056-3 in the United Kingdom with regard to siphonic roof drainage systems; it does not alter any of the provisions of that standard.

BS 8221:2000 Code of practice for cleaning and surface repair of buildings
BS 8221-1:2000 Code of practice for cleaning and surface repair of buildings This standard provides guidance on removal or partial removal of deposits from the original surface or substrate of a building. Advice is given on the principal cleaning methods in use and the characteristics of surface deposits. Guidance is given on cleaning natural stones, clay brick, calcium silicate brick, glazed and unglazed terracotta/faience, and cast concrete and concrete products such as cast stone, concrete brick and concrete blockwork.
BS 8221-2:2000 Code of practice for cleaning and surface repair of buildings. Surface repair of natural stones, brick and terracotta
This British Standard provides recommendations for surface repair of natural stones, clay brick, calcium silicate brick, glazed and unglazed terracotta, and faience masonry in buildings. It covers repointing and selection of mortars, and provides guidance on treatment for protection of surfaces. Surface repairs of concrete and structural repairs are not covered by this code of practice. For guidance on structural repairs, reference should be made to BS 5390 and BS 5628-1.

Journal of Constructional Steel Research
Volume 58, Issue 1, January 2002, Pages 21-70
Abstract
Introduced in this paper are (1) some computer programs for static/dynamic elasto–plastic
finite displacement analyses used in designing steel bridge structures, (2) the ultimate strength
and design methods of steel plates, stiffened plates and columns made of high strength steel
subjected to compression, (3) seismic design and retrofitting methods of new and existing steel
bridge piers after the Hyogo-ken Nambu Earthquake, and (4) friction type joints and tension
type joints with high strength bolts and development of high performance high strength bolts
in Japan. These are some topics which the authors are concerned with among new technologies
of steel bridges under development in Japan, such as development of high performance steel,
new fiber materials, new types of bridges, performance based design methods, seismic design
method against earthquakes of level 2 like the Hyogo-ken Nambu Earthquake, and bridge
management system. 2002 Elsevier Science Ltd. All rights reserved.
