WebCompression strength parallel to the grain is much lower than tensile strength. During a bending test, initial yielding occurs on the compression side, followed by visible compression failures and enlargement of the compression zone. The neutral surface shifts toward the tensile side of the specimen as the tensile stress continues to increase. WebTimber-concrete composite systems are widely used in Europe, North America, and Australasia, primarily due to their good mechanical performance in terms of statics, dynamics, and seismic response.
