A prestressed concrete beam 223mm x 677mm has the following service loadings PDL=67 KN PLL=44 KN *Concentrated load acts on the midspan wDL=12 kN WDL=17 kN. Loss of prestress at service loads is 20 % Throughout the span, the tendons are located 83 mm below the N.A.. If the allowable tensile stress is 2.96 MPa, and considering the point of maximum moment, calculate the required Prestressing force in kN.

Engineering Economics Principles

Engineering economics (engineering economy) is a sub-field of economics to study the use and application of the economic principles in the engineering analysis of decisions along with the systematic evaluation of the advantages of project costs inclusive of engineering design and analysis. It emphasizes microeconomics (a subset of economics) for researching the behavior of people in the decision-making process of assigning and determining multiple alternatives to the usage of some of the restrained resources and merging economic theory and engineering practice in a practical manner. It depicts the logical framework of economics in addition to the analytical application of statistics and mathematics.
