Guangzhou New Library Project is divided into South and North Tower,both of whose plans are shaped half-moon.It is used a mixed frame structure system which is composed by reinforced concrete steel reinforced concrete and steel structure.The main feature of this project is leaning structure-the columns of south tower are leaning in north directions and the columns of north tower are leaning in both directions.Generally,the largest inclination is about 18°.South and north tower are connected to a common structural system to resist external effects by the beams which are installed at the top of eighth floor.Due to the leaning feature of Guangzhou New Library Project,horizontal displacement will be continuously,increasing during the construction process.So,it may lead to a considerable deviation between the structural construction-completed configuration and the structural design configuration that will result in main structure such as the beam at eighth floor can't be stalled.Therefore,there is necessary to construction simulation and pre-set deformation value to compensate for the deformation of the structure during the construction process,so as to achieve the purpose of configuration control.The main study of the thesis includes the following two aspects:1.Construction process simulation.The forward-analysis method is used,in this paper, under the "activation" and "passive" function on structural components and load of MIDAS/GEN process.2.Calculation of pre-set deformation value.In order to easily install eight-beam,pre-set deformation value is calculated using of forward iteration method in this paper.Paper studies the changes of internal force and displacement of structure during the construction process,and the pre-set deformation value for smooth installation of eight-beam. At the same time,paper gives important basis for process and production of components construction installation and construction monitoring. |
