Embodiment Construction

[0034] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0035] The invention provides a site selection method for an emergency shelter in consideration of the hazards of secondary falling objects in a building earthquake.

[0036] Such as figure 1 As shown, the method includes three parts: 1. Calculation of the distribution of falling objects in building groups, 2. Uncertainty analysis of earthquake motion, 3. Site selection of emergency shelters.

[0037] 1. Calculation of the distribution of falling objects in the building complex

[0038] 1.1 Calculation of seismic response of building complex structures

[0039] The calculation of the seismic response of the structure adopts a multi-layer shear model. The model simplifies the floors to particles, such as figure 2 As shown, structural response data su...

Abstract

The invention provides a site selection method for an emergency shelter with consideration of building seismic secondary falling object harm, and belongs to the technical field of disaster prevention and reduction of civil engineering. According to the method, firstly, a multistory shearing model and a falling object motion analysis are combined, and a calculation method of the distribution range of building group secondary falling objects in a set seismic oscillation is provided; then with consideration of the uncertainty of the seismic oscillation and the dangerousness of a regional earthquake, based on a gradual dynamic increment time-history analysis, a calculation method of the distribution probability of the building group falling objects in the design cycle is provided; finally, through superposition of the probabilities of different building falling objects, the influence range of the building seismic secondary falling objects is determined, and then the available safety range is determined for site selection of the emergency shelter. The method is applied to a residential community in Beijing, the emergency shelter is replanned according to seismic falling object calculation, so that the safety of the emergency shelter is improved. By means of the method, a site selection method which considers influence of the building seismic secondary falling objects is provided for site selection of the emergency shelter.

Description

technical field [0001] The invention relates to the technical field of disaster prevention and reduction in civil engineering, in particular to a site selection method for emergency shelters in consideration of the hazards of secondary falling objects caused by building earthquakes. Background technique [0002] In an earthquake, the hazard of falling objects caused by the damage of non-structural components outside the building is one of the main causes of personal injury. In the Northridge earthquake in the United States, more than half of the injuries were caused by falling objects. Therefore, in my country's "Code for Design of Disaster Prevention and Refuge Sites" (Ministry of Housing and Urban-Rural Development. Design Specifications for Disaster Prevention and Refuge Sites GB51143-2015, China Construction Industry Press, 2016), it is considered that there should be a reliable disaster-resistant design to ensure that the building (structure) When the buildings will not...
