With the questionnaire of needs structure and the method of talking, we investigated 406 students in Wenzhou teachers college randomly, who come from different grades and classes.

This study take Maslow s theory of need levels as basic theoretical framework, and combined with Aodefu s ERG theory to empirically test quantitatively the research needs structure and research incentive satisfaction based on self-designed questionnaire.

Some discussions on Code for Dynamic Machine Foundation Design(GB 50040-96) are had,including mass-spring-damper model,dynamic foundation parameters,load combination and structural requirements.

Some recommendations have been raised for design of connecting beams according to"Technical Regulations on Concrete Structures of High-rise Building"(JGJ3-2002),and studies on structural requirements of connecting beams and ductility measures,etc.

The structural requirement of frame structural joint core was proposed,its seismic checking calculation requirement and method were illustrated.

Combined with practical work and based upon analysis of the mechanical behaviors of wall the disposal principles and construction requirements of wall in composite structure are proposed.
