Prestressed Concrete Design

Prestressed Concrete Piles

A state of the art presentation on prestressed piling as used throughout the world is discussed in this General Report to the FIP Symposium on Mass-Produced Prestressed Precast Elements in Madrid, Spain, May 1968. Historical information, design data and notes along with manufacturing techniques, installation practices, discussion of problems and failures and a complete bibliography are all cove...

Ductility of Prestressed and Partially Prestressed Concrete Beam Sections

D analyses of structures responding elastically to ground motions recorded during severe earthquakes have shown that the theoretical response inertia loads are generally significantly greater than the static design lateral loads recommended by codes. Hence, structures designed for the lateral earthquake loads recommended by codes can only survive severe earthquakes if they have sufficient ducti...

Factorial Design Approach in Proportioning Prestressed Self-Compacting Concrete

In order to model the effect of mixture parameters and material properties on the hardened properties of, prestressed self-compacting concrete (SCC), and also to investigate the extensions of the statistical models, a factorial design was employed to identify the relative significance of these primary parameters and their interactions in terms of the mechanical and visco-elastic properties of S...

بهینه یابی در طراحی مخازن بتن پیش تنیده prestressed concrete tank design optimization

در شاخه سیویل و در ساخت سازه ها همیشه ایمنی و بعد از آن هزینه مهم ترین پارامترهای مورد نظر مهندسان در طراحی بوده است . و در این میان هزینه می توانسته طرحی را مقبول کارفرمایان و توجیه پذیر از نظر اقتصادی نماید. بنابراین در صورتیکه بتوان تمام طرحهای قابل قبول از نظر سازه ای را در برابر هزینه بری های هر کدام مقایسه نمود و بهترین طرح را، انتخاب نمود ایده آل مهندسین خواهد بود. در این پایان نامه به ت...
