It was modeled as a double layer wire mesh reinforced in the 75 x 3000 x 3000 mm (Width:Length:Height) size of the wall with opening of 1200mm x 1200mm in the middle of the wall. Material properties used are Grade C30 for normal weight concrete and the minimum yield strength of the wire mesh is 485 N/mm2. The wall panel analyzed under direct compressive axial load acting directly in the middle of the wall (without eccentricity) with pinned support at the top and bottom of the wall model. The analysis shows that the wall panel failed by crushing because of the slenderness ratio of the wall is 20. If the panel got a higher H/tw, it will fail by buckling. Higher stress concentration appears at the upper sharp comer of the opening and it proves the assumption made before. The provision of opening somehow produces discontinuities or disturbances in the normal distribution of stresses that lead to the stress concentration to happen at the abrupt change of opening.
