Problems solved by technology

However, since the secondary frame structure in the primary and secondary frames consumes most of the seismic energy, it is the main energy-dissipating component, so the yield damage is serious under the earthquake

Abstract

The invention discloses a tuned shock absorbing frame structure of a cast-in-place main frame-prefabricated sub-frame. The tuned shock absorbing frame structure comprises multi-layer of internal prefabricated sub-frame beams, a plurality of internal prefabricated sub-frame columns, outer cast-in-place main frame columns and multi-section of cast-in-place main frame beams, and further comprises a plurality of sliding shock absorbing structures and a plurality of vibration isolation supports, wherein the outer cast-in-place main frame columns are provided with a plurality of brackets from top tobottom in a layer height; two sides of the internal prefabricated sub-frame beam at each layer are respectively connected with the brackets on both sides of the layer by the sliding shock absorbing structures; and the bottom end of each of the prefabricated sub-frame columns is connected with the cast-in-place main frame beam at each section through the corresponding vibration isolation support.By adopting the tuned shock absorbing frame structure, the energy absorbing and shock absorbing capability of a building structure can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of energy dissipation and shock absorption of building structures, and in particular relates to a tuned shock absorption frame structure of a cast-in-place main frame-a prefabricated secondary frame. Background technique [0002] Earthquakes have been one of the most harmful natural disasters to humans since ancient times. According to incomplete statistics, in the past century, more than 20 cities including Tangshan in my country were destroyed by the earthquake. my country is located at the junction of the circum-Pacific seismic belt and the Eurasian seismic belt, the seismic fault zone is very active, and seismic activity occurs frequently. In recent years, there have been major earthquakes such as the 8.0-magnitude earthquake that occurred in Wenchuan, Sichuan on May 12, 2008, causing about 70,000 deaths and more than 370,000 injuries; the 7.0-magnitude earthquake that occurred in Ya'an, Sichuan Provinc...
