PROBLEM TO BE SOLVED: To provide an apparatus, a method and a program for predicting building vibration that are capable of predicting with high accuracy the state of vibration within a building due to external vibration. SOLUTION: A CPU 22 obtains acceleration information showing acceleration at each frequency of vibration produced at a source of excitation according to an exciting force applied to the source of excitation located outside the building, damping factor information showing a damping factor at each frequency of vibration due to ground between the source of excitation and the building, loss rate information showing a loss rate at each frequency of vibration when the vibration is input to the building via the ground, and resonance amplification factor information showing a resonance amplification factor at each frequency of vibration in the building. Based on the acceleration information, damping factor information, loss rate information, and resonance amplification factor information obtained, the CPU 22 then derives a physical quantity showing the state of vibration produced inside the building according to the exciting force, and displays on a display 18 information showing the derived physical quantity.
