A dry viscous spring strut is provided having at least a top outer housing member, a bottom outer housing member, a shear spring elastomerically associating the top outer housing member to the bottom outer housing member, a selectively pressurizable gas chamber, a subchamber disposed in association with the gas chamber including a plurality of elastomeric particles, a rigid structural member associated with the top outer housing member, and a bearing portion associated with the bottom outer housing member to receive the structural member. The structural member is received in the bearing portion to bear side loading forces to the strut and to limit nonaxial deformation of the strut. Relative movement between the top and the bottom housing members operates to stress the shear spring and the elastomeric particles, vary the pressurization of the gas chamber and subchamber, and vary the positioning of the structural member relative to the bearing portion to absorb shock and dissipate energy imparted to the strut. At least one of the housing members includes a casing wall contiguous to the shear spring configured in an arcuate bell-like form to accommodate deformation of the shear spring during compression of the strut.
