Structural fatigue strength in crane design rules in China;

This paper emphatically expounds some matters needing attention in operation of intelligent building,analyzes the cause why intelligent building does not operate normally;puts forward some concrete measures for strengthening working out of the intelligent building standards and design criterion.

According to the city thermal net design criterion, this paper analyses the problems of heating guideline, calculation of yearly heating consume, selection of heating water temperature, chloride ion erosion of stainless steel equipment, heating adjusting of hot water, design demand of using waterpower to calculate pressure.

Standards of intelligent architecture and importance of establishing design criterion are also mentioned in this paper.

The comparison of the setting-lever of the reliability of concrete structural design codes between China and America;

Discussion on Related Ventilation Clauses in "Design Code for Highway Tunnel;

Calculation and analysis of comprehensive safety factor for basic members in design code for concrete hydraulic structures;

Compared study on Chinese and American concrete structural design standard on reinforced bar

The stipulation of counting the cutting length of steel bar scatters in various kinds of design standard and final acceptance standard.

In the light of a practical example, this article points out the existing problems with the design standards of horizontal flow type grit chamber,and discusses the factors affecting the grit deposit.

This paper introduces the application of the steel-concrete composite beams to practical projects, the corresponding design specifications, development course of theoretical research and current situation, as well as the application of the steel-concrete composite beams to the typical long-span bridge projects at home and abroad.

The present situation of vertical rigidity tor the existing railway bridges under the action of Zhong-live load as stipulated in the railway design specifications in China and the proportional relationship between various load working conditions and Zhong-live load are analyzed.

The current domestic engineering design specifications need to be modified correspondently in order to meet the new requirements.
