Earthquake Disaster Evacuation Tent Village Housing Cables And Structure Study Of The Planning

Article two parts :Part According relevant laws, villages development conditions analysis, villages population size, planning construction land scale villages construction environment construction land layout the long perspective pairs dalian village overall disaster land conducted planning. Planning consider that nearest principle, known principle, refuge with relief timing principle, multipurpose principle, flexibility principle.Overall disaster planning program, new buildings accordance local seismic fortification grade (7 degrees) construction, unsafe public buildings and residential should be reinforcement, dangerous should dismantled. The village committee office building west of Highland Square planned as refuges for evacuation. Press forward population size quantity 646 calculation, refuge Plaza area 2,400 square meters. Dalian Village fixed refuges for evacuation service radius 2 km about walk 1 hour within can arrive.Part II For tightrope refuge tents design part (tents located dalian Village Committee office west Heights Square), according corresponding architecture, structure design national standard structural Selection and design. For cable prestressed simulation adopts sap2000 simulation. On tightrope refuge tents from design to installation conducted detail. Construction when default foundation basis reserved steel wells, peacetime covers closed ground flat for a large Plaza. Steel, cables, tarpaulin related tools according category mounted different colors box. Green behalf steel, red behalf tightrope.Yellow behalf tarpaulin, blue representatives tools. All boxes and related tools stored in default storage room. Disaster after Just sequentially open, assembling. Among major vertical bearing system adopt seamless, transverse bearing system stainless Sok. External maintenance structure using double PVC fiber tarpaulin.Finite element analysis software using sap2000 refuge in tents analog cable. For one of the basic principles and methods were introduced to simulate the pre-tensile stress the basic principle is to pull the deformation is equal to cool the resulting deformation. By choosing a reasonable element type, material properties, modeling methods such as simulation of cable shelter tents in the normal state of bearing capacity and to analyze the results. Cable tensile stress required for the 1.556KN, tension capacity to meet the requirements and conditions consistent with manual assembly.
