Brace is usually installed in aseismic ceiling to keep the aseismic capacity. In the case of high depth ceiling, brace crosses hanging bolt. Experience of several tests show qualitatively that buckling capacity become larger than that of Euler buckling by combining the brace to hanging bolt. Evaluating formula for buckling capacity of brace supported by spring at midpoint is derived and its practical formula is proposed, in which supporting spring ratio ξ and capacity amplifying ratio η are introduced. Buckling capacity of 3 case of lateral loading test results show good agreement with evaluated values by proposed formula.
