We have, in the preceding pages, considered the framing which enters into a building of light construction, such as an ordinary dwelling house, but there are certain classes of structures which call for heavier framing, or framing of special character. Among these may be mentioned battered frames, or frames with inclined walls; trussed partitions; inclined and bowled floors; special forms of reinforced beams and girders; the framing for balconies and galleries; timber trusses, towers and spires, domes, pendentives and niches; and vaults and groins. These subjects will now be taken up and discussed, and the methods employed in framing such structures will be explained.
