A truss configuration with a curved top chord and straight bottom chord connected by vertical or angled members, resembling an archer's bow. Bowstring trusses combine the efficiency of arches with the constructability of straight members.
Named for its resemblance to an archer's bow, with 'bowstring' referring to the straight bottom chord. The architectural term developed in the 19th century as engineers adapted the visual metaphor to describe this hybrid structural form.
