Study On Wind Induced Disturbance Effect Of T-Shaped Plane Light Camping Houses

T-type light camping houses are widely used in medical security sites,and are also common in rescue and disaster relief sites,engineering construction sites,and military camping sites.However,such houses are often of light quality and thus sensitive to wind load response.At present,in view of the monomer building wind resistance design at home and abroad were detailed norms and research relatively mature,but the houses in the engineering practice often present a group arrangement form,and in engineering application and there is no theory of such houses research for reference,namely the theory research and engineering practice,unable to meet the needs of engineering practice.In order to make full use of the shielding effect beneficial to safety,avoid the amplification effect with potential safety hazards,and design and use safely in practical engineering application,it is urgent to carry out research on the wind-induced interference effect of such housing groups under regular layout.To study T plane light camping house decorate in the rules under the wind-induced interference effects,in this paper,the research content in atmospheric boundary layer theory and computational fluid dynamics theory,using the finite element analysis software,and combining the TTU wind tunnel test,analysis and determine the turbulence model and computational domain size,algorithm,grid form,discrete format and grid number determination and selection of parameters,the key techniques such as to establish the rule arrangement under T plane numerical wind tunnel light camping house groups.On this basis,according to the usage of light camping house,the design of lightweight camping house group arrangement and goal of houses,with transverse spacing density coefficient,the longitudinal spacing between the density coefficient,0 degrees,45 degrees and 90 degrees Angle for the analysis parameters of wind of monomer building,80 kinds of working condition of double row 12 houses numerical simulation of the building surface wind pressure distribution of target is obtained and negligible interference conditions,introducing the interference factors,concluded that decorate house rules amplification effect and shade effect area and conditions,and is suitable for the group wind load shape coefficient of wind resistance design.The results show that: under the group layout,the roof and local protrusions are greatlyaffected by the disturbance effect,especially the wind pressure near the windward surface changes greatly;Under the regular of layout,the influence of house spacing on the interference effect between houses is greater than the influence of wind direction Angle.When the spacing reaches 5 times the length of the house,there is no interference between houses in any wind direction.
