NONLINEAR ANALYTICAL MODEL FOR REINFORCED CONCRETE PANELS UNDER IN − PLANE STRESSES Study on nonlinear analytical method for reinforced concrete wall structures ( Part 1 ) * 亙 洋 且 G 翫 長 鮴 嬲 ぬ An analytical model for a cracked reinforced concrete ( RC )element is proposed on the basis Qf in ・ plane shear tests of RC panels. The proposed modei can deal with both compressive failure of concrete strut and sliding failure along crack surfaces . ThrQugh cQmparisons of the analytical results of RC
