In this paper, temperature conditions for thermal movements analysis of the measured building which was shown by the previous paper in A. I. J. No. 376 and two buildings which were measured by Dr. KAZUO OHNO are discussed. The calculations for analyzing the measured buildings utilize a three-dimensional elastic analysis program by the Framework Method. The analysis is based on two assumptions; (a) Thermal movements are caused only by the ambient temperature. (b) Thermal movements of beams and columns are free only in the axial direction and those of walls and slabs are free only in the longitudinal direction except the thickness direction. The results obtained were compared with the field-measured movements. The conclusions are as follows: (1) A three-dimensional elastic analysis taken into account the atmospheric tempera-ture and room temperature can be used in a prediction of thermal movements caused by temperature changes over an extended period of a few months or half a year. (2) In the building with heat insulation, under the assumption that the temperature conditions of all structural members were constant, the analytical results do not agree with the actual measurements. However, assuming that the appropriate temperature conditions is considered in the three blocks ((1): the roof and beams at the top storey, (2): external walls and beams and columns in the plane of structure where contains its walls, (3): the other structural members) , the analytical results approach the actual measurements.
