Wall is an important structure to protect the inside of a house or building. The wall also functions to carry and forward loads from the roof. Wall collapse can be a structural failure that can make people die. Therefore, it is necessary to do a wall analysis in the form of modelling to the wall that will be built to review the damage that can be occur. There are 3 types of the wall, that is 3 meter, 3,5 meter and 4 meter of width wall with variation of high 2,5 meter until 4 meter and horizontal and vertical load direction. The walls are modeled using software STERA FEM. This research was conducted to see the pattern of stress distribution and to determine the high effect on wall stiffnes. The result from this research shows that the wall stress value affects to wall stifness because the wall stress value affects to modulus elasticity. The higher modulus elasticity, the better stiffness.
