Abstract:

A brace for cyclic loads includes a tube having first and second ends and a tube wall and a tube axis. The tube wall defines a plurality of first bores radially arranged about the first and second ends of the tube. The first bores extend through the tube wall along first bore axes that are substantially aligned axially with the tube axis. A first end fitting is removably attached to the first end of the tube at an end of the first end fitting. The end of the first end fitting defines a plurality of second bores that have second bore axes. The plurality of second bores are substantially aligned axially and radially with the plurality of first bores. A second end fitting is removably attached to the second end of the tube at an end of the second end fitting. The end of the second end fitting defines a plurality of third bores having third bore axes. The plurality of third bores are substantially aligned axially and radially with the pluralities of first and second bores.
