This report discusses construction system, batching and mixing of concrete, construction work and inspection system, and summarizes the current problems and suggestions for enhancing reliability of concrete structures.
In order to rationalize RC buildings which have long span frames, precast concrete girder that is pre-stressed on pretension system is developed. Bond characteristics of PC strand after earthquake are examined and confirmed. The developed girder is applied to a high-rise condominium that is being built in Sendai. Measured data on this building are also reported.
