Shaking Table Test Study and Theoretical Analysis of High-rise Building with Truss Transfer Story
Yunian International Commercial Affairs Building is a complicated structure of high-rise building with transfer mega-truss.Combine with Shanghai Ynnian international commerce building, a model shaking table test and a ETABS finite element analysis of Shanghai Yunian international commerce building are carried out to research its seismic behavior.A 1:25 scale micro-concrete model of the building above is [...]
Anlysis of Seismic Resistance of the High-Rise EBSF Structures
Eccentric braced steel frames is refined resistant-lateral system based on concentrically braced frames,and is a kind of steel structure of high-rise building with better seismic-resistant and energy-dissipation,When an earthquake is coming,the dissipative link of an eccentrically braced frame becomes plastic earlier. then it consumes the energy of earthquake by its plastid deformantion and accordingly the [...]
Finite Element Analysis and Seismic Influence Studies on the Structure of Tower Crane QTZ630
Tower crane is special equipment commonly used in the construction of high-rise buildings. The design of tower crane is directly related to people’s lives and property safety. At present, however, the traditional analogy and static calculation are playing main roles in the design and bringing tower crane some problems such as high weight, irrational structure [...]
The Anti-seismic Performance Analysis of Steel Reinforced Concrete Frame Supported by Frame-concrete Core Structure
Over the last decade, high-rise hybrid building was universally adopted. At first, the steel frame-concrete core structure was applied mostly common, but the stiffness of the concrete core is much larger than external steel frame, so the seismic performance of them can’t act coordinately and reasonably and it maybe not able to play the role [...]
The Seismic Response Analysis of Concrete Filled Steel Tubular Arch Bridge
In the past years, the destructive earthquakes frequently occurred in the world, which brought great damage to the safety of people’s life and property. The indirect disaster due to the earthquakes result in collapse of bridges regarded as the lifeline engineering, which will lead to more loss of life and property. Therefore, it is necessary [...]
Thin Walled High-Pier Construction Phase Response Analysis of Wind Loads
With the development of transport,in our country high pier and large-span bridge construction is carry out rapidly,because of the increasing in height of bridge piers,wind resistance of the construction process pier security has became seriously problem.In this paper,based on the research of key technologies for the engineering background of provincial highway S318 line Sanmenxia Westzhangcun [...]
Study on the Spatial Seismic Responses of Long Span Self-anchored Suspension Bridge
Self-anchored suspension bridge,having a beautiful appearance,competitive in cost,is being more used recently.With the increasing of the span the demand of aseismic is becoming more important,so it is very necessary for us to research its dynamic property and seismic response.Some basic theories of certain seismic analysis were reviewed firstly in this paper.Then a new time-history analysis [...]
The Analysis of Viscous Dampers Impact on Anti-seismic Performance of High-rise Structure under Action Near-field Earthquake
Compared with the common non-near-field earthquake excitation, the near-field earthquakes because of its long-period pulse of the role of speed, will be more strongly on the structure of velocity and displacement of the impact of the disaster to the city is also very heavy, so in order to ensure that the structure in the near-field [...]
Prestressed System Analysis and Study on Seismic Behavior of Large Cantilevered Steel Roof Structure
Prestressed steel structure is popular with the construction industry at home and abroad in the past 20 years. Large-scale prestressed steel project built in China have been nearly a hundred in recent years, the size of its engineering and technical levels have reached the international advanced level. However, due to the comparatively short developed time, [...]
Experimental Analysis and Anti-seismic Behavior Research on Improved D-type Eccentrically Braced Steel Frame
Eccentrically braced frame is a new lateral-loads-resisting system developed recently for buildings in high-intensity earthquake regions and in which D-type eccentrically braced structure is one of the most commonly used structures for resisting seismic.In this thesis,we first present the theory and features of D-type eccentrically braced frame,as well as its disadvantages,based on recent research and [...]
