多功能活动心计算书.doc

摘 要 多功能文化中心是小区举行活动的重要场所，是整个小区的标志性建筑。本文包括三个部分，建筑部分，结构部分，基础部分，其中以结构部分为重点，结构部分包括屋盖结构的设计和钢筋混凝土框架设计。 本次设计采用了大跨空间结构。大跨空间结构是一种具有很大覆盖面的新型结构，它具有刚度大，抗震性能好的特点，在这众多的结构形式中，正放四角锥网架应用的很广泛。 网架结构是由焊接钢管和焊接空心球组成，网架结构采用轻型屋面材料作为屋顶，这样就减轻了屋面荷载，达到了节省钢材的目的。网架结构还具有轻质高强、美观等优点，而这一系列的优点刚好满足了多功能活动中心的要求。 网架结构的计算也伴随着计算机的发展和软件的更新得到了简化。计算模型的建立更加符合实际情况，所以计算结果更加的精确。 本次设计中采用了四角锥网架结构来满足设计和使用的要求。 关键词： 大跨空间结构、正方四角锥网架 Abstract The versatile center is a very import place which would hold some spiritual activities.It is the symbole of the block.There are three parts in the thesis,architecture part ,the structure and the basement design.Among these parts,the structure design is more important which include the roof design and the reinforced concrete frame design. In this design ,we use the large-span space structure. Lage-span space structure is a new structure system which has lage coverage .It has the characteristic of large special rigidity and good anti-seismu capacity.I n these structure forms,the pyramidal space grids is used more widely than others. Spatial grid structure is made up of welding tube and welding hollow ball,which uses light roofing material as the roof system.Therefore it can not only reduce the load of the roof system ,but also save the expense of the whole design.Moreever,it has the merits of light weight but high strength and beauty ,which fits the meets of constructing the versatile center well. With the development of the computer and the continuous upgrade of the sofware ,the calculation of spatial grid structure has been simplified..Thus the results of calculation are more accurate ,people will apply the conclusions to the project without too much modification . In this design we adopt pyramidal space grids to meet the demand of the project.
