PROBLEM TO BE SOLVED: To simply construct an earthquake-resistant reinforced wall having high tenacity by using a high-tenacity FRC material (a short-fiber reinforced cement composite material).;SOLUTION: When an earthquake resisting wall 10 is to be extended at an opening 7 in the frame of a reinforced concrete-constructed existing column 2 and an existing beam 3, form at only in one side is erected under the existing beam 3, short fibers are mixed towards the forms and concrete and mortar are mixed, a composite material having improved tensile and being strength and tenacity is manufactured by three-dimensional random blending of the fibers, and high-tenacity FRC material (a short-fiber reinforced cement composite material) 12 in which tensile strain exceeds 1% is sprayed.;COPYRIGHT: (C)2000,JPO
