From Thailand began to suffer from earthquake. In the north of the country, such as the earthquake on May 5, 2557 in Dong Ma Da District, Mae Lao District, Chiang Rai Province. As a result, many buildings have been damaged as a result of research projects that will be designed to deal with earthquake. Using the design principles, the building can reduce the force caused by the earthquake. Using material absorbed force. And reduce building weight by using Expanded Polystyrene Foam (EPS) material. At a density of 1.5 pounds 3 inches thick to apply to a building wall. Instead of masonry walls, which are heavy weight. They can also reduce heat transfer rate and soundproof too. The floor of the building will use EPS foam. The density of 2 pounds, 6 inches thick, instead of the floor to help reduce the weight of the building. When the weight of the building less. It will lessen the impact of earthquakes. This can reduce the damage to the building.

Based on the simulation results of the earthquake with the SAP 2000 program, it was found that buildings built with heavy brick monoliths were subjected to stronger earthquakes than buildings built of foam walls. By considered at the earthquake force which attack to the joint of building. At the joint node 3 of the brick wall building (case 1 node 3) has a value of 3723.33 kgf. The foam wall building (case 2 node3) has a value of 1963.33 kgf and the force at the joints node 4 of the brick wall building (case 1 node4) has a value of 3916.29 kgf, while the foam wall building (case 2 node4)has value of 2156.29 kgf indicated that the building made of foam walls had less force than the brick building.
