Analyse of the modular structures of populations on Leymus chinensis and Hierochloe glabra in different succession series in cutting grassland;

Based on the modular theory and with the analysis of relatedness degree adopted in the grey system theory, the correlation of the ecological factors and the modular structure of young tree population in Cephalotaxus mannii, which is distributed in five places in Hainan island China, was investigated.

Applications of mathcad in the design of structural members;

The paper generalizes the experience on the steel structure design,discusses the features,loads and function,structural member,joints and shock resistance of the door-type light rigid frame building.

It introduces the researching and developing circumstances of the functions of explosive lode on architectural structure, analyzes the anti-detonation performance of structural member and node, and summarizes the researches on structural continuous collapse, which to offer theoretical criterion for further researches on explosive load.

The steel has been used for many years for sheeting and decking but is now being used for structural members such as roof trusses and stud walls of steel framed houses.

Among numerous architectural details,details which origin from structural members have the most ability to reflect the art of construction.

The importance of aseismic design in the attached element and non-structural element;

On the engineering background of offshore platform, fatigue reliability analysis method of structural component with crack defects was established.
