Then the geometrical nonlinear seismic time-history response behaviors of the cylindrical latticed-intersected-three-dimensional-beam-system (LITDBS) reticulated mega-structure were analyzed.

Dalian China Petrol Tower is a complex super high-rise structure,with reinforced-concrete(RC) tube and outer grid truss tube.

Some aspects of the construction are emphasized,such as the installation of special-shaped spatial truss,the installation and stretching of stay cable,the welding technology of homemade thick steel plate at negative temperature.

Making use of the principle of Beam String Structure,we made a new cantilever spatial truss string structure(CSTSS).

Study on economical efficiency of the staggered-truss system under vertical load;

Structural performance of the staggered-truss system;

The working mechanism of shear connector of the staggered-truss system between reinforced concrete plank and steel chord was analyzed based on theoretical analysis and value computational methods,and details such as reasonable styles,types and quantity of the shear connector were introduced via a calculated example.

Analysis and comparison of comprehensive performance of all kinds of truss forms in staggered truss system;

This paper presents an analysis of the structural disposal characteristics of staggered truss system.

The staggered truss system is a prospective steel structure system with advantages of large lateral stiffness, lightweight, low cost and convenient layouts of architectures.
