摘要
PROBLEM TO BE SOLVED: To provide a visual checking device enabling a building construction planner planning the construction of his (or her) own building or house, a student learning construction, or a scholor researching earthquake-proof buildings to simply experience the earthquake-proof performance of a building or a house by observing it. ;SOLUTION: A building model of earthquake-proof structure or earthquake suppressing structure is arranged on a vibration board 1 to be vibrated by frequency similar to the vibration of earthquake and a fixed scale 6 capable of visualizing vibration generated by the building of earthquake-proof structure or earthquake suppressing structure arranged on the board 1 is projected from a fixed board other than the board 1. Plural building models of general structure having respectively different height are also arranged on the board 1. In addition, the period or amplitude of the board 1 can be changed.;COPYRIGHT: (C)1999,JPO
