Problems solved by technology

[0008] In addition, the traditional cast-in-place beam-slab structure, due to the integral pouring of the floor slab and the beam, causes the negative moment bearing capacity of the beam at the beam-column joint to exceed its design capacity, making it difficult to form the strong-column-weak-beam failure mode in the conceptual design, resulting in The column or beam-column joint area fails first, causing the building to collapse

Abstract

The invention discloses a reinforced concrete periodic damping structure which comprises a vertical supporting structure and a horizontal force transmission structure. The vertical supporting structure comprises columns, walls, primary beams and secondary beams, the horizontal force transmission structure comprises floor slabs and roof plates, the vertical supporting structure is formed by overcall pouring, the horizontal force transmission structure is arranged on the vertical supporting structure, an elastic body element is arranged between the bottom surface of the horizontal force transmission structure and the vertical supporting structure, and elastic body elements are arranged between adjacent lateral surfaces of the horizontal force transmission structure or lateral surfaces of the horizontal force transmission structure and the vertical supporting structure. The reinforced concrete periodic damping structure enables the floor slabs or the roof plates in a concrete building structure to be used as principles and methods of periodic damping elements, can guarantee that the floor slabs and the roof plates achieve normal using functions, can also reduce earthquake response of buildings, and simultaneously can guarantee that an energy consumption mechanism is formed by the main vertical supporting structure according to an ideal plasticity model.

Description

technical field [0001] The invention relates to the field of anti-seismic technology of reinforced concrete structures, in particular to a construction and construction method in which a concrete floor slab or roof slab is used as a periodic structural element and other structural components to form a periodic structure for shock absorption. Background technique [0002] With the in-depth investigation, analysis and research on earthquake damage of building structures, the anti-seismic and vibration control technology of buildings has also developed vigorously and achieved phased results. Among all kinds of anti-seismic technologies, the basic seismic isolation technology is to install a seismic isolation layer with reset function composed of rubber seismic isolation bearings and damping devices between the building foundation, the bottom or the substructure and the superstructure to prolong the entire construction period. The natural vibration period of the structural syste...
