| With the rapid development of national economy and the convening of largecommunity cultural and sports activities, the long span space is needed more andmore. In this context, the construction technology of large span structures has beenrapidly developed and improved. The structural form of large span structures is oneof the core technologies in the construction technique of large span structures. Inrecent years, the scholars at home and abroad to improve the structure span abilityand economic performance put forward a variety of new type large span buildingstructures, such as cable-supported structure, cable dome structure, cable-membranestructure, cable-stayed structure, arch-supported structure. In this paper, theclassification, static and dynamic performance, non-uniform temperature effect,rotation and sliding construction technology of the arch-supported structures, havebeen analyzed and studied.In the second chapter, the classification of steel arch structures, the core part ofthe arch-supported structures, was firstly carried out. Based on the classification,some new steel arch structures are presented, such as suspended cable-archpre-stressing composite structures, cable-stayed-supported pre-stressing compositeand so on. Based on the classification of arch-supported structures, the structuralbehaviors of suspen-dome with stacked arch structures under any load case isanalyzed, and the analysis results shows that there is a remarkable effect ofnon-uniform temperature load induced by solar radiation on the nodal displacementand member stress.In the third chapter, taking the arch-supported structures in Shandong Chipingstadium (suspen-dome with stacked arch structures) and Jinzhou stadium(arch-supported canopy structure) as two examples, the temperature distribution andthermal effect of the arch-supported structures under solar radiation is investigated.It is concluded that the solar radiation has a large effect on the structural behavior ofarch-supported structures and it has to be considered in the future design. In order toimprove the temperature healing construction, a active healing construction methodis presented.In the fourth chapter, taking the suspen-dome with stacked arch structures inShandong Chiping stadium for an example, the wind-induced effect and seismicresponse analysis consideration of traveling wave effect were carried out, and thefollowing conclusions were obtained:1) the range of nodal wind vibrationcoefficient for suspen-dome with stacked arch structures is1.0~1.4; The nodal wind vibration coefficient of upper single-layer lattice shell is in the range of1.0~1.2; thenodal wind vibration coefficient of out-door arch structures is in the range of1.1~1.3,which is higher than that of upper single-layer lattice shell; the average of nodalwind vibration coefficient for overall structures is1.12;2) under multiple-supportseismic excitation, the maximum stress in the intersection of out-door arch and innerdome is relatively larger; earthquake affecting coefficient is larger, therefore, hereneeds more care in the design process.In the fifth chapter, the construction technique of rotating sliding method iscarried out systematically, including the mechanical analysis in construction process,the choose of machine and equipment, sliding system, construction measure andsafety step and so on. The above achievements have been written in to the localstandards in Hebei province: Technical specification for sliding construction of largespan spatial steel structures.In the sixth chapter, taking the Erdos swimming gymnasium as the background,a1:100scale model was constructed. Using this model, the feasibility and theadvantages of rotating sliding construction method is verified.In the seventh chapter, taking the Erdos new airport structures as a example,Construction mechanics and time-varying mechanics have been introduced simply inthis paper. Process analysis model of construction was designed by using Unit Birthand Death Technique, according to multistage cumulative analysis. Deformation andinternal force of main truss in Terminal of Erdos Project in different stage offalsework sliding technology was calculated, then the result of Unit Birth and DeathTechnique analysis and block analysis were compared, also the effect of hingedsupport and fixed support. The conclusion can be used to instruct the construction ofthis project.In this text, the structural behaviours and construction technique have beeninvestigated systematically, and the static and dynamic properties, non-uniformtemperature effect and rotating sliding construction technique were obtained, whichcan be a important reference for later design and construction of the arch-supportedstructures. |
