Transforming Tangshan Grade Schools Into Seismic Shelters Based On The Concept Of Green Architecture

In recent years,although the total number of shelters has been increasing,but with the expansion of the city and the increase of the population,the number of shelters in most cities is still insufficient and the location distribution is uneven.And most of the places of refuge use public facilities such as parks and squares with open spaces as places of refuge.The advantages of grade schools as places of refuge based on the principle of nearby service are ignored.In this paper,Tangshan grade schools located in the earthquake zone are chosen as the research object,which is based on the concept of green building.Based on the investigation of the distribution,scale,functional composition and spatial characteristics of grade schools in Tangshan City,this paper combines the design of possible shelters to adapt to the climate change in the four seasons under the influence of the climate conditions in Tangshan city.This paper analyzes the suitability of grade schools as places of refuge and the development potential of grade schools as places of refuge in Tangshan area.At the same time,starting from the research of human behavior psychology,this paper seeks for the laws of phototaxis and sense of belonging of asylum behavior psychology,and obtains the corresponding demand for temporary living space,supporting facilities and external space in special time and space.Based on the CFD system’s PHOENICS software and ECOTECT software,the optimization research and analysis simulation of refuge space are carried out.In order to improve the strategy and theory of the optimal design of primary and secondary schools as shelters,the quantitative indexes of different seasons are put forward.And then summed up the green design method of grade school shelter.A lot of basic work has been done for the grade schools within the scope of study,such as the visual analysis of the location of shelters and the distribution of grade schools in the core urban area,the analysis of outdoor wind pressure and ventilation of single building,etc.,which is suitable for the construction of shelters in Tangshan area.This study can improve the efficiency of urban space utilization.Make full use of the space in the shelter.In order to relieve the psychological pressure of asylum behavior,the comfort degree of space use should be improved.Combined with the physical environment for comprehensive optimization,to find the appropriate green design methods when primary and secondary schools as shelters.It can provide reference for the development of this kind of refuge building.Improve the planning and design system of shelters.
