Theoretical Analysis On Improving The Construction Efficiency Of High - Rise Buildings

As the contradiction between the increase in city population and the limited land resources is increasingly serious, the main resolution is the tall building structure. With the limitation of the steel types used in the buildings, reinforcements are generally not chose according to the real stress of the components in the process of construction. However, adopting reinforcing bars based on the experience of layer merger can avoid producing several types of steels on account of the reinforcement according to the actual stress. At present,there are many tall building structure has been studied theory and methods,but less for layer merge method often used in engineering research,the paper inventive proceed from the layer merge method of tall building structures used in the construction process research,come up with a new method of merging layers reasonable judgment. Reinforcement method for enigeering experience has made innovation.The main contents as follows:First, introduce the development of the high building structure and the research status at home and abroad so as to systematically summarize and combing through the given computing methods of the tall building structure at present.Second, take a certain tall building structure as the analytic object and work out the load-carrying capacity of the structure. And then analyze the consequence and judge its rationality. Next, extract the datum of the load-carrying capacity of the main reinforcements from the typical girder and then figure out and analyze the error values generating by merger from the second to sixth layer.Third, work out the permissibly optimal error value among reinforcing bars εby the model number of the spiral reinforcement. And then set error proportion ηin the optimal error range, and judge the rationality of the number of merger layers, which is then popularized.Finally, sum up the research findings and point out the shortages of the new method in the research.
