Directivity Effect in the Peak Ground Acceleration Fields and Attenuation Relations -- A Case Study of the Ms 8.0 Wenchuan Earthquake Jinjun Hu 1,a, Lili Xie1,2 and Yongqiang Yang1 1Institute of Engineering Mechanics, China Earthquake Administration, China 2School of Civil Engineering, Harbin Institute of Technology, China ahujinjun@iem.net.cn Keywords: Ground motion field, Attenuation relation, Directivity, Wenchuan earthquake Abstract.
While the directivity effect in short period ground motions was not proved until 1978 by Bakun who studied two small earthquakes in middle California, this is more interesting to engineers.
This earthquake caused severe engineering damage with huge economic loss and death toll.

Research and Application of External Prestressing Curved Beam’s Tendons Minyuan Huang1, a, Zongren Zou1, b 1College of Civil Engineering and Mechanics, Central South University of Forestry and Technology, Hunan, Changsha, 410004, China aHmy555@163.com, bChriszoulove@163.com Keywords: External Prestressing; Curved Beam; Tendon Diameter; Anchoring Position; Strengthening Works; Optimal Design; Control Parameters.
Introduction Early in eighteen twenties, the external prestressing technology was applied to engineering practice in abroad.
The scientific and favorable technical guidance can be provided for actual engineering of the external prestressing.
Engineering Application With the vigorous development of engineering technology, requirements of the structure bearing are also gradually increase.
These advantages of performance greatly promote the use of external prestressing curved beam in practical engineering application.
