1968年十勝沖地震による建築物の被害について

Abstract

Considerable damages are reported to have been caused in buildings, particularly, in reinforcedconcrete buildings, due to an earthquake which took place in the offing of Tokachi on May 16, 1968. The paper first surveys the damages, and then discusses the details on the examples ofseverely damaged buildings; it describes their structural systems, maj or damages and principalcauses of the damages. Finally, attention is called on the shear failure of reinforced concretecolumns, and reference is made to the past experimental studies on the shear failure. The discu-ssion extends to the points claimed to be important for the design of reinforced concrete framesagainst earthquakes.
