Analysis of ductility features in bearing failure process for cable-strut arch structures under the load combined full span and half span loads Youbao Jiang1, 2, a, Guoyu Liao2, b 1 Key Laboratory of Concrete and Pre-stressed Concrete structure of Ministry of Education, Southeast University, Nanjing 210096, China 2 Changsha University of Science and Technology, Changsha, 410114, China ajiangybseu@163.com, b379257623@qq.com Keywords: Cable-strut Arch structures, Ductility, Half span load, Full span load.
Steel is assumed as an ideal elastic-plastic material, fy = 345MPa.
Thus, the main failure mode would be failure of arch truss in plane and the material nonlinearity of cable may not be considered.

Introduction The corrosion process, which acts spontaneous, affects the integrity of the materials and of the structures which use these materials to be built to.
Different materials with anticorrosive properties and deposition techniques for protective (overlapped) substrates of these materials were developed in order to prevent and control the steel corrosion [1-2].

The doping concentration was varied from 0% to 50% by controlling the different deposition rate between these two materials while the total thickness was fixed at 100 nm.
Introduction Electronic devices based on organic materials are a promising technology for this decade.
Nowadays, there have been many applications using organic materials such as organic light emitting diode (OLEDs), organic photovoltaic devices (OPVs), organic field effect transistors (OFETs) and organic gas-sensor.
Among the hundreds of organic semiconducting materials, pentacene have been intensively studied due to its distinguishable optical and electrical properties as well as chemical and thermal stability.
