High house steel space frame disgncharacteristicssteel structure disgn Should comply with special design procedures and who Top civil building steel structure technology regulations & throughout , should be strictly requests the reasonable structure layout and structure of the system, and the reasonable selection of technical and economic performance.
2: steel structure of the seismic design should be two stage design, the first stage design according to the calculation more severe earthquake seismic action, the second stage according to Abraham in seismic action, and check the respectively displacement and interlayer lateral ductility ratio limit requirements.
3: strict requirements on lateral deformation control, in order to avoid the effect and comfort and retaining structure is seriously damaged and requirements,steel structure disgn Must meet specified peak displacement and layer displacement requirement, the structure of the lateral stiffness is often design of the control indicators, in addition, for reference to consider comfortable requirements and avoid the occurrence of horizontal wind vibration, still should check wind load of the structure under the action of peak acceleration and threshold wind velocity, etc.
4: seismic design of structures to node seismic capacity calculation and member slenderness ratio, panel width (high) thickness ratio, through welding requirements, such as support for the seismic structural measures, in the new & who Seismic code and throughout Are strict, special requirements.
5: for design calculation complexity and high difficulty, require the use of more accurate and complete calculation method and means, such as a wind tunnel test to determine the wind load size box number, seismic design must be adopted to shock type decomposition method, the elastic-plastic analysis, the time history analysis method, and the corresponding special computer software, etc.
6: the material selection of steel products requirements higher, more strict. As for the heavy plate, h-beam, gun nails, high strength bolt, choose, as well as to Z to tensile properties, welding performance, impact toughness and ductility performance, such as the selection of technical performance, design requirement for personnel to the steel properties and the application requirements have more understanding.
7:steel structure disgnManagement and procedures also have strict requirements, such as to transfinite high-rise steel structure seismic design, the scheme shall be subject to and who The overrun highrise engineering seismic fortification review committee of experts and throughout Through review. At the same time, high-rise steel structure of the calculation and analysis generally should check double calculation.
In our country in the future to design more high-rise steel structure building,. So that the steel structure building do our best, make steel structure building into people's heart, building a more beautiful even more spectacular steel structure building to steel structure building the world advanced level.
