Weekly Detailed Course Contents
| Week | Topics |
|---|---|
| 1 | The concept of ""prestige"" and the history of prestressed concrete. Prestressed concrete structural materials. |
| 2 | Prestressing techniques: externally prestressed, internally (wired) prestressing; pre-stretching, post-stretching.Patent pre-tensioning techniques. |
| 3 | Prestressed concrete calculation methods: calculations in operating conditions, final limit status checks. Pre-stressed cross-sectional effects on bars. Assumptions about stress and strain. |
| 4 | Pressure center, sectional efficiency (efficiency), central core and account, pressure core, tensile core, limit core. Absolute minimum of prestressing force. Critical section, critical clearance. |
| 5 | Cable passage core, cable passage area. Determination of cable passage area with absolute minimum of prestress. Critical cross section is residual and biasing force. Prestressing force in composite sections. |
| 6 | Cable passage core, cable passage area. Determination of absolute minimum prestressed cable crossing area. Critical transverse section residual and bending strength. Prestressing force in composite sections. |
| 7 | Cable provision and cable withdrawal, cable after all. Prerecorded losses: Friction loss, loss of anchorage seats. Examples of friction and anchorage loss losses. Pre-stress loss due to concrete elastic shortness: after pre-stretching and stretching. Preventive losses due to concrete shrinkage and shrinkage |
| 8 | Prestressed steels are loosened and relaxed, which leads to premature failure, loss attempts. Records of related Turkish and foreign regulations lost. |
| 9 | Final limit state checks: rectangle and T section. Determination of limit values for consumables. |
| 10 | Calculation and determination according to shear forces: shear-shear accessory account. Sewing equipment and account in composite sections. Other evaluations of composite sections. |
| 11 | Control of prestressing. Measurement errors and elimination. |
| 12 | Constant (hyperstatic) structures. Calculation of prestressed indeterminate internal forces: equivalent load method, impact line method. |
| 13 | Construction techniques without scaffolding in reinforced concrete structures: construction methods, riding methods, other methods. |
| 14 | Construction techniques without scaffolding in reinforced concrete structures: construction methods, riding methods, other methods. |
