jailcd2024058: Prefabricated Mobile Building and Its Timber-steel Hybrid Material Technology for Low-carbon Tourism from Daiwa Japan

Abstract

The current paper studied the prefabricated mobile building and its timber-steel hybrid material technology for low-carbon tourism from Daiwa Japan. A steel hybrid brace is a buckling restraint brace that combines steel and wood, using steel as the core material and wood as the restraining material. Buckling is a phenomenon in which a member bends significantly when it receives a load above a certain level. A "buckling restraint brace" consists of a "core material" sandwiched between "restraint materials" to prevent buckling when force is applied to the brace. "D-NΣQST" is an energy-absorbing load-bearing wall that not only withstands large tremors, but also effectively absorbs seismic energy and reduces the amplitude of tremors. By quickly stopping the shaking of the building, we prevent catastrophic damage to the structure. Advanced technology called sustained earthquake resistance realizes safety against repeated large earthquakes. This technology from Daiwa Japan can be used in mobile accommodation for low-carbon tourism in China.
