A shock absorbing suspension comprises a pair of parallel, spaced mounting plates (12), two pairs of counterrotating D-frames (13), and two connecting bars (11). Each pair of frames is slidably attached to the inner side of one of the mounting plates by two grippers (14). The scissoring connecting bars are disposed between the pairs of frames to link the frames together. A resistance mechanism (65) is mounted on each gripper for substantially resisting the rotation of each individual frame in one direction only, such that the suspension will substantially resist being compacted together, but can be freely extended apart. In one application, the bottom mounting plate is attached to the ground, while the top mounting plate is attached to and supports a building. When at rest, the resistance mechanisms will provide enough resistance to allow the suspension to support the building without being compacted. When the ground jolts upwardly in an earthquake, the suspension will be compacted to absorb the upward motion of the ground. But, when the ground jolts downwardly, the suspension will freely extend. As a result, the suspension will safely isolate the building from the violent ground movements.
