Traditional load applying methods are simple with little automatization, and most are done only on the plane so that complex spatial joint experiment is hard to achieve.

In this paper,combining with the design of The Three Museums of Wuxi,the design,finite element analysis and joint experiment of cast-steel joint are introduced.

Summarizing of plane crisscross joint test;

A series of prototype nodes with industrial characteristics are proposed to avoid repeated development of typical scene units.

It introduces the process of prototype testing of reducing Tongguan elevation by optimized peach floods occurred in 2006 and points out the following main effect of testing: a) reduced Tongguan elevation by 0.

A corresponding analytical system named TDGS was proved to be quite effective in simulating a prototype test specimen.

On the base of the uplift model tests and prototype tests on foundation of transmission line tower,the uplift performance of expansive soil is deeply researched.

According to the result of a pullout prototype test of the connection between a prestressed concrete pipe pile of1200mm in diameter and a pile cap,the failure form,bonding mechanism and influencing factors of the connection are discussed.
