中文摘要:
      型钢混凝土转换梁由于其承载力高、刚度大、延性好及耐火、耐久性能优越等诸多优点得到越来越广泛的应用,但是也存在着施工工艺复杂、施工难度大、施工过程危险性大、容易造成与结构设计不符等难题。本文结合贵阳市花果园办公一号楼的特殊工程,采用数值模拟和现场实时监测等分析方法,分析在各种施工工况下,大跨度型钢混凝土转换梁的受力状态,提出了转换梁施工的起拱高度及位置,并对转换梁施工过程受力安全状况进行预控,其研究方法和结论可为类似工程的设计和施工提供借鉴。
英文摘要:
      Owing to section steel reinforced concrete transfer girder has high load capa city, high stiffness and good ductility and excellent refractory and durability so on many other advantages, it is more and more widely applied. But it also presences complex construction craft, difficult construction, great danger in the construction process. At the same time it is likely to cause discrepancies with the structural design。 Combining Office Building I as a special project in Guiyang City Huaguo Yuan,employing many methods such as numerical simulation and field real-time monitoring,this article analyses stress state of the long - span section steel reinforced concrete transfer girder under different conditions ,proposes camber height and location of transfer girder in construction,and pre-controls security force of transfer girder,whose research methods and conclusions provide reference the design and construction for similar projects .
