Abstract: A two-part clamping assembly and method for applying the clamping assembly to intersecting I-beams is disclosed. The clamping assembly is particularly beneficial at uniting the undercarriage I-beams of a mobile dwelling to intersectingly smaller I-beams of an auxiliary support system, during moderate and/or severe seismic disturbances. The clamping assembly includes a two-part connector designed to tightly engage the upper flange of the lower and smaller I-beam in such a manner that a clamp-lip horizontally protrudes over and is parallel to the bottom flange of the upper undercarriage I-beam. The clamp-lip is engaged at the bottom flange to the undercarriage I-beam, in the event of an earthquake, enabling the undercarriage I-beams to pickup the auxiliary support system. At the cessation of quake conditions, the undercarriage I-beams are reposited to the I-beam of the auxiliary and emergency support system.
