Outside unstability loading device greatly ensure that when single Pin frames planar add Cyclic Loading that one direction stress is without plane
Unstability, so as to which experimental condition be made to be consistent with really condition.In addition, there is following advantage using adjustable anti-unstability loading device：
It makes that simple, easy for installation, controllability is strong and cost-effective, prevents laterally losing suitable for load test reciprocal in test specimen plane
Surely.
The slide plate of profiled holes is made out to be pushed against in H profile steel flange of beam both sides using reinforcing bar and bolt fixation, it is made to be fastened on one
It rises, the pulley being welded in lateral support makes it be contacted with special-shaped slide plate by mobile lateral support, and slide plate is with examination during loading
Part moves back and forth in the horizontal direction under reciprocating load, and pulley position is constant, and the two generates relative displacement, avoids plane
Outer unstability, so as to which experimental condition be made to be consistent with full-scale condition.The device have make simple, strong applicability, it is easy for installation and into
The advantages that this is suitable.Be conducive to unidirectional load test research, there is vast potential for future development and design application value.
Disclosed above is only the specific embodiment of patent of the present invention, and still, the embodiment of the present invention is not limited to this, is appointed
What what those skilled in the art can think variation should all fall into the protection domain of patent of the present invention.
Therefore there is significant economic benefit using this structure.
