This calculation method is simple and ease of use, it benefits application of this kind of joint in actual structure engineering and provides the basis and reference for design of the semi-rigid connection.
Therefore, it is necessary to develop a simple and accurate calculation model for the M-θ relationship of end-plate connection, which meets the requirements in actual structural engineering design and the elastic-plastic analysis.
However, the nonlinear curve is replaced by line segment for convenient calculation in practical engineering.

It can provide references for the actual construction and ensure the similar engineering construction.
Because the tunnel engineering is located in the shallow crust, it has small variations about temperature of surrounding rock, and quantity of thermal radiation are directly proportional to the difference of the absolute temperature of object with the fourth power, so it is negligible.
Take the tunnel engineering for example, internal heat transfer mainly exist in the rock mass ,convective heat transfer occurs mainly between in the surface of the tunnel and the air flow inside.
The application of more field coupling analysis on tunnel engineering.

The Crack Control of Reinforced Concrete Structures Wang Gang Civil and Architectural Engineering College of Panzhihua University,Panzhihua 617000,China 16160100@qq.com Keywords : Reinforced Concrete Structures; Crack Control; Quality Supervision Abstract: With the continuous development of the level of China's political, economic and social, the construction industry also obtained great progress.
There is a very serious problem In the course of engineering construction which is the crack control of reinforced concrete structures.
So, one of the important factors of the lack of government supervision of power is to affect the relevant engineering construction in our country industry level not up to standard.
Secondly, chaos in China's engineering construction quality control of industry environment makes our country carried out any related a new model must obtain a great degree of market acceptance.

The merit of the proposed methodology is computational efficiency without compromise on accuracy and this is demonstrated through the engineering problem.
Introduction Many practical engineering structures are ill defined and imprecisely known to be modeled and analyzed by conventional deterministic procedures[1,6].
Examples of fuzzy systems are: (1) The preliminary design of complex engineering structures and machines in which the effect of manufacturing and assembly on the design parameters is fuzzy; (2) The analysis of aging aerospace, naval, nuclear, civil and military structures and machines, where the effect of loading and environmental conditions on the structural/material properties are not precisely known; (3) The design and analysis of space structures, which require extensive testing under extreme operating conditions of the space environment such as microgravity, extreme temperature, and vacuum conditions.
The merits of the proposed methodology which include computational efficiency on accuracy have been demonstrated through the engineering problem.
