Research status and development of dry goods sharing cast light steel composite structure
The cast light steel composite structure is suitable for low and multi-storey buildings, and has the advantages of high stress efficiency, earthquake resistance, energy saving, green environmental protection and so on.
Recently, the paper “research status and development of cast light steel composite structure” co written by Professor Cao Wanlin of Beijing University of technology, academician of Chinese Academy of engineering and Professor Zhou Xuhong of Chongqing University was published in Volume 23 and 12 of CSCD journal “progress of building steel structure”.
China’s low and multi-storey buildings are mainly distributed in villages and towns, and their construction area accounts for about 50% of the national construction area.
The paper summarizes the research progress of cast cold-formed thin-walled steel structure, cast light steel light concrete structure The development process, system composition and seismic performance of typical cast light steel composite structures, including layered cast light steel frame flexible support structure and cast light steel composite frame light steel composite shear wall structure.
At present, more than 90% of township houses have extremely weak seismic performance, poor energy-saving effect, serious resource waste and environmental pollution in the construction process.
The popularization and application of cast light steel composite structure in rural construction is not only conducive to improving the quality of rural buildings, but also conducive to saving resources and energy, improving labor production efficiency and quality safety level, reducing the waste of construction time and materials, reducing energy consumption and emission during construction, and helping the construction industry achieve the goals of “carbon peak” and “carbon neutralization”, Promote green and low-carbon development in rural areas-.
The technical characteristics, standard system, industrial construction and engineering application of the above structures are analyzed, some problems in the research of cast light steel composite structures are put forward, and the future development direction of cast light steel composite structures is prospected.
