The struts and ties are called bracing bars.
The houses are built of wood and bamboo; and as the use of diagonal struts is not practised, the walls soon lean over from the force of the winds.
The compression members are of timber, except the struts and bottom chord panels next the river piers, which are of steel.
The Howe truss had timber chords and a lattice of timber struts, with vertical iron ties.
In the Pratt truss the struts were vertical and the ties inclined.
