Problems solved by technology

Due to the calculation of the seismic action effect of the overall structure, it is impossible to calculate the phase difference of the seismic action of the structures on both sides of the connecting body. There is almost no force, and the rear part has a high vibration mode. When the two wings move in opposite directions and rotate, this reverse vibration forces the connecting body to participate in the work and bear the force, and the quality of this part of the mode shape is relatively small, so it is impossible to calculate the two sides of the connecting body. Due to the influence of reverse translation and rotation effects, the seismic distortion of the connecting body obtained by this method is much smaller, and there are potential safety hazards

Embodiment Construction

[0017] In order to facilitate the understanding of the technical solutions provided by the embodiments of the present application, the nouns involved in the present application are briefly described first.

[0018] Mode shape decomposition response spectrum method: A method used to calculate the seismic action of multi-degree-of-freedom systems. This method uses the acceleration design response spectrum of the single-degree-of-freedom system and the principle of mode shape decomposition to solve the equivalent seismic action corresponding to each order mode shape, and then combine the seismic action effects of each order mode shape according to a certain combination principle. Thus, the earthquake action effect of the multi-degree-of-freedom system can be obtained.

[0019] Time-history analysis method: Time-history analysis method is a dynamic analysis method that directly solves the differential equation of motion of the structure step by step. Through the time-history anal...

Abstract

The invention provides an earthquake action determination method and device, relates to the field of building structure engineering, and is used for accurately acquiring the earthquake action of a thin waist-shaped connector. The method comprises the following steps: acquiring gravity loads of single-side structures from the ith floor to the nth floor of the thin waist type building, an earthquake shear coefficient difference value of the ith floor, gravity loads of single-side structures from the (i + 1) th floor to the nth floor, and an earthquake shear coefficient difference value of the (i + 1) th floor; according to the gravity loads of the single-side structures from the ith floor to the nth floor, the earthquake shear coefficient difference value of the ith floor, the gravity loads of the single-side structures from the (i + 1) th floor to the nth floor and the earthquake shear coefficient difference value of the (i + 1) th floor, determining the earthquake action borne by the connector of the ith floor.

Description

technical field [0001] The present application relates to the technical field of structural engineering, in particular to a method and device for determining earthquake action. Background technique [0002] Slender buildings are often used in high-rise and super high-rise buildings, especially in super high-rise residential buildings. In the prior art, the conceptual design and corresponding structural measures for the connectors in the thin-waisted buildings are given, but the prior art does not provide a clear calculation method for how to obtain the seismic action of the connectors through calculation. [0003] At present, the existing methods generally use the overall structure mode decomposition response spectrum method and time history analysis method to calculate the seismic action effect of the connector. Due to the calculation of the seismic action effect of the overall structure, it is impossible to calculate the phase difference of the seismic action of the struc...
