Calculation Theory And Finite Element Analyze Of Concrete Tension Member

In practical engineering, we usually come up against tension members. For example: the low level columns of high-rise building with wind load or earthquake load; the tensile leg of reinforced concrete twin columns in industry building under crane load. It is easy to ensure the bearing capacity through analysis the tension members and the damage characteristics. There is little special research of tension members. But the tension member is a necessary part of the reinforced concrete member. The flexural member also looks like a tension member under the axes load with infinity lateral distances. It can help the students clear about the contact of tension member and the flexural member.The reinforced concrete textbook' content builds on the Code for Design of Concrete Structures. But the expressions' mechanical concept in the code is unclear. The students just remember the expressions, but it is hard to understand the meaning.As a chance of building the simple course, this article tries to build the formulas for calculating tension member by use of the stress-strain curve of concrete and steel, use the mechanical method analysis the expressions in the Code. Then the article compares these formulas with the Code or the test to prove its correctness.Three problems have been mainly solved in the paper as the following:1. Analyze the axial loaded member, which has established the formulas by use of the stress-strain curve of concrete and steel, and has compared them with the Code's.2. Considering the changing of the reinforcement ratio and concrete strength, the effect to the concrete member's mechanical behavior is analyzed.3. The finite element models of axial tension member and eccentrical tension members are established with ANSYS finite element program.4. Introduced development status,the definition and the characteristics of the network course. Based on these studies, the paper put forward the syllabus of the network course, which is reference to apply for national perfect curriculum.
