Download Durability Design Of Concrete Structures By A.Sarja And E.Vesikari Easily In PDF Format For Free.
Control Of The Durability Of Concrete Structures Has Gained Increasing Importance At The Design And Maintenance Stages Of These Structures. Most Of The Current Durability Problems Of Concrete Structures In, For Example, Bridges, Dams And Façades Of Buildings Could Have Been Avoided With Systematic Durability Design. Such Design, However, Requires Both An Overall Methodology And Detailed Calculation Models Of Actual Deterioration Processes. Safety Requirements And Margins Must Be Defined For Service Life. This Report Represents The First Systematic Attempt To Introduce Into Structural Design Both A General Theory Of Structural Reliability And Existing Calculation Models For The Commonest Degradation Processes.
In Fact, The Introduction Of Systematic Durability Design Will Mean Better Utilization Of The Existing Research Results For Systematized Control Of The Service Life Of Concrete Structures During Design. These Pioneering Attempts At Systematic Durability Design Will Help To Formulate New Ideas And Identify The Needs For Further Research Of Degradation Processes And Their Calculation Models. Durability Calculations Enable Not Only Priority Ranking Of Materials And Structural Factors, But Also Produce Numerical Values Of Factors For The Intended Service Life. The Idea Of This Report Is To Present The Methodology Of Durability Design In Such A Way That It Can Be Combined With Traditional Mechanical Design.
This Procedure Utilizes Current Results With Regard To Safety And Performance Under Static, Fatigue And Impact Loading. The Greatest Change Is The Highly Improved Design Regarding Durability. Through Durability Design, All Durability Parameters Such As The Concrete Cover, Durability Properties Of Materials, Amount Of Reinforcement And Dimensions Of The Structures Are Calculated, Taking Into Account In Each Case Actual Degradation Processes And, Where Necessary, Their Interaction. In Order To Understand The Design Methodology And Calculation Methods, A Fairly Extensive Introduction Is Given To The Statistical Background. The Reliability Theory Of Structures Is Applied To Durability Safety Principles. A Number Of New Definitions Are Also Presented. The Planning And Writing Of This Report Were Done In Close Cooperation By The RILEM TC 130-CSL Working Team Comprising The Following Persons:
Dr Carmen Andrade
Mr A.J.M.Siemes
Mr Erkki Vesikari (Technical Secretary)
The Members Of RILEM TC 130-CSL Were:
