ABSTRACT OF THE DISCLOSURE A resilient sealing member for use in an expansion joint comprising a tubular body having an internal truss structure which includes a pair of intersecting crossbars extending between the sidewalls and bottom wall of the tubular body. The sealing member, being of the low pressure type, further includes a vertically disposed compression bar extending between the midportion of the top wall of the member and the intersection of the crossbars to exert a downward pressure on the crossbars during compression of the member to thus reduce some of the sidewall pressures in a manner resulting in a substantially level pressure profile across the vertical dimension of the sidewalls.
