Description

technical field [0001] The present disclosure generally relates to the construction field, and specifically relates to an energy-dissipating support structure, an energy-dissipating support frame system and a construction method thereof. Background technique [0002] As the volume of construction increases exponentially, prefabricated buildings have become an increasingly common construction method. The prefabricated construction method prefabricates components in the factory, and assembles, connects, pours the components at the construction site, and finally forms the final building. [0003] The massive destruction and collapse of buildings in earthquakes is the direct cause of earthquake disasters. Therefore, how to achieve a more stable connection and how to better resist natural disasters such as earthquakes are important indicators related to the safety performance of buildings. [0004] The traditional anti-seismic method is to dissipate the seismic energy through t...
