Lateral loading fixture apparatus and achievement method of same

The invention discloses a lateral loading fixture apparatus comprising a first concaved clamping sleeve, a second concaved clamping sleeve, a first embedded clamping head, a second embedded clamping head, an end-bearing board, a vertical connection board, a transversal stiffening rib board, a fastening bolt, a test piece, and a loading instrument; wherein the first embedded clamping head is arranged in the first concaved clamping sleeve, the second embedded clamping head is arranged in the second concaved clamping sleeve, and the test piece is arranged between the first embedded clamping head and the second embedded clamping head. According to the structure, the embedded clamping heads can be changed to achieve lateral loading on test pieces in different shapes and sizes. The apparatus effectively solves a problem that a lateral loading fixture apparatus in the prior art only allows lateral loading on test pieces in single special specification or requires customization of fixtures for members in different si
