Recognizing that PBL shear key in all aspects of civil engineering play an increasingly important role, firstly, to do a simple analysis and discussion on the ultimate strength of PBL, followed by the use of MIDA FEA finite element model was established, then its static power loads such as displacement and stress are analyzed and compared.
This formula further improves the formula (1) which has the only safe carrying capacity estimates in considering the basis of engineering significance by using deformation compatibility principle, considering the ability to resist transverse reinforcement slip and the shear strength reduction factor of 0.12 times [6].

The proposed method puts forward a universal way for sensor placement of the civil engineering structure.
In recent years, quite a lot of attempts have been done to determine the best ideal sensor locations of civil engineering structures.
In other words, some methods still can not be used effectively in engineering project [6].
So far, previous studies have failed to present a universal method for sensor placement of civil structures.

Preface It is our pleasure to welcome you to the 2014 International Conference on Advanced Engineering Materials and Architecture Science (ICAEMAS 2014) in Xi'an, China.
ICAEMAS 2014 is the first conference dedicated to issues related to Materials Science, Civil Engineering and Architecture Science, Mechanical Engineering, Manufacturing Technology, Automation, Management Engineering.
A major goal and feature of it is to bring academic scientists, engineers, industrial researchers together to exchange and share their experiences and research results about most aspects of Materials Science, Civil Engineering and Architecture Science, Mechanical Engineering, Manufacturing Technology, Automation, Management Engineering, and discuss the practical challenges encountered and the solutions adopted.
The program consists of invited sessions, and technical workshops and discussions with eminent speakers covering a wide range of topics in Materials Science, Civil Engineering and Architecture Science, Mechanical Engineering, Manufacturing Technology, Automation, Management Engineering.

As an effective detection method of stress distribution, the dynamic photoelasticity has been wide used in stress analysis, such as detection of mechanical structure, civil engineering and water conservancy etc.
Research stress wave propagation in different interface has an important reference value for engineering structure design and construction.
This method is regarded as a kind of important optical measurement method being  wide used in machinery structure, civil engineering, water conservancy and other aspects of stress testing and analysis because it has the advantages of full field, non-contact, high accuracy, high sensitivity, strong intuitive and reliability in dispose stress concentration problem [6-9] .
These results for engineering structure to prevent shock load design provide a reliable experimental basis.

Discussion of Different Methods of Strengthening Masonry Walls with Constructional Column Cheng Wang1, a, Yongkun Luo1,Xiaolong Xu1 Civil Engineering, Southwest Jiaotong University, Chengdu, Sichuan, China wangchengxx@sohu.com Key words: Masonry, Strengthening, Finite element, Constructional column Abstract.
With the rapid development of economy and the civil engineering discipline, the seismic performance of existing masonry wall can't satisfy the codes and regional seismic requirements.
It has engineering sense for the strengthening work.
This paper uses a finite element software- abaqus to analyze these two methods of strengthening masonry walls with constructional column, and make a comparison with the original wall to verify the feasibility and engineering practical value of the methods.

Aspect ratio of crack is one of key factors of fatigue strength prediction in engineering design and civil structures using fracture mechanics.
Introduction While it is very important to detect crack size and shape in civil engineering, it is hard to measure their precise shapes and/or mechanical factors.
