Abstract
After an introduction discussing design assumptions/limitations, tables are presented of standard sizes of purlins and ceiling joists for housing in some Indian social forestry species. The tables aim to provide a ready reckoner for design, construction and inspection of houses constructed from such timbers. The species included are Abies pindrow, Acacia catechu, Acacia nilotica, Albizia lebbek [A. lebbeck], Albizia procera, Alnus nepalensis, Anogeissus latifolia, Azadirachta indica, Dalbergia sissoo, Gmelina arborea, Picea morinda [P. smithiana], Pinus roxburghii, Pinus wallichiana, Syzygium cumini, Terminalia arjuna.
