The great concept is a building that can withstand the collapse due to earthquake vibrations, and have the flexibility to reduce vibration. Principally there are basically two: the rigidity and flexibility of damping structures. Rigidity principle structure makes the house more solid structure of the shock. Proved, that the structure of reinforced concrete rigid as if made with good vibration damping earthquake well. This means attention to the structure actually made at the time of development to stronger and more rigid. Rigidity of the structure can avoid the possibility of building collapse during an earthquake occurs.

The columns and tie beams should be strong and supported by a good foundation too. Flexibility Principle: The possibility of building structures can be moved in small scale, for example by using the principles of relationship-roll on the footstool footstool burden. The definition of the relationship is the kind of pedestal roll loading relationship can move in a small scale to reduce vibration. This is one example.

The principle of the use of lightweight materials and ’springy’: that is to use materials that do not light more dangerous when collapsed, and the more light that is not excessively burdensome to the existing structure. For example wood structure that can accept timber movement in the relationship between the scale of the earthquake was. The principle of mass separated: that is split in several parts of building a smaller structure, so that this structure is not too big, too long because if the earthquake had to reduce vibration greater.
