An apparatus for testing the load bearing strength of an architectural structure includes a top holding assembly, a hydraulic cylinder, a bottom holding assembly, and a bracing member. The hydraulic cylinder is disposed below the top holding assembly, and has a top end. The bottom holding assembly is mounted on the top end of the hydraulic cylinder, and cooperates with the top holding assembly to hold the architectural structure therebetween. The bottom holding assembly includes a peripheral wall. The bracing member has a plurality of bracing rollers disposed around and slidably abutting against the peripheral wall of the bottom holding assembly so as to absorb lateral horizontal stress which may occur during the testing of the architectural structure under compression.

I claim: 1. An apparatus for testing the load bearing strength of an architectural structure, comprising: a top holding assembly; a hydraulic cylinder disposed below said top holding assembly and having a top end; a bottom holding assembly mounted on said top end of said hydraulic cylinder and cooperating with said top holding assembly to hold the architectural structure therebetween, said bottom holding assembly including a peripheral wall; and a bracing member including a plurality of bracing rollers disposed around and slidably abutting against said peripheral wall of said bottom holding assembly so as to absorb lateral horizontal stress which may occur during the testing of the architectural structure under compression. 2. The apparatus as claimed in claim 1, wherein said peripheral wall of said bottom holding assembly is rectangular and has four side walls, two pairs of said bracing rollers being mounted adjacent to each of said four side walls of said bottom holding assembly, said bracing member further including a plurality of roller seats each of which carries one pair of said bracing rollers. 3. The apparatus as claimed in claim 2, wherein each pair of said bracing rollers are spaced apart vertically. 4. The apparatus as claimed in claim 1, wherein said bottom holding assembly includes a seat body having a receiving recess on top thereof and a spherical body corresponding to and slidably confined within said receiving recess, said peripheral wall of said bottom holding assembly being disposed between said seat body and said bracing rollers of said bracing member. 5. The apparatus as claimed in claim 4, wherein said hydraulic cylinder includes a plunger extending upward at said top end of said hydraulic cylinder to support said seat body of said bottom holding assembly. 6. The apparatus as claimed in claim 4, wherein said bottom holding assembly further includes a flat plate mounted on said spherical body, and an insulating plate mounted on said flat plate. 7. An apparatus for testing the load bearing strength of an architectural structure in a fire simulating site where a top end of the architectural structure is to be held by a top holding assembly, the apparatus comprising: a bottom holding assembly adapted to hold a bottom end of the architectural structure and including a peripheral wall; a hydraulic cylinder having a top end supporting said bottom holding assembly; and a bracing member including a plurality of bracing rollers disposed around and slidably abutting against said peripheral wall of said bottom holding assembly so as to absorb lateral horizontal stress which may occur during the testing of the architectural structure under compression.
