Designing And Application Of Pretensioned Space Lattice Structure

Pretensioned space lattice structure is a new kind of space structure which develops very fast in recent years.Through taking the pretensioning with tendon ,the space lattice structure could effectively improve the weight of bearing,control the distortion of the structure, minimize the cost of the engineering.This paper introduces the developing tendency of the space structure and the application of the pretensioned space lattice structure,Summarize the analysis method and relation between lattice structure and pretensioned space lattice structure. Dissertate the space pole-truss displacement method,tendon working principle,set forth the method of optimal design and whole process design. Includes the use stage design and construction stage design of pretensioned space lattice structure.This paper takes the example of two huge palaestra, particular introduced the whole process for the designing of pretensioned space lattice structure,from the selection of the plan, thinking of the design,the scheme for the dispose of tendon,the selection of reasonable tendon pull , structure calculate,to the last the analyse of calculate result, the analyse of structural dynamical capability,and the economy compare of several plans, particular analyzed the advantages and disadvantages of this kind of structure.this kind of structure has wide application foreground in engineering.
