### Rational Analysis and Design of Prestressed Concrete

2018-11-1 Rational Analysis and Design of Prestressed Concrete Beam Columns and Wall Panels Noel D. Nathan Professor of Civil Engineering University of British Columbia Vancouver, British Columbia Canada Precast concrete columns are often east and shipped in lengths extend- ing over two, three, or more stories.

Precast concrete columns are often east and shipped in lengths extending over two, three, or more stories. In consequence, they are frequently long and slender, at least until jointing is complete, so that handling stresses may give rise to problems. Similarly, precast loadbearing wall panels for light industrial or warehouse structures are generally required to be very tall, again

Characteristics of prestressed concrete members which affect the method of analysis are described, and it is noted that "rational analysis" is often required. Construction of a computer program to perform such an analysis of component members is discussed, and a program is described in detail n an appendix. Several examples are included.

In conjunction with sectional equilibrium and compatibility, simplified yet rational design equations are then developed to predict the ultimate stress increase in external tendons. Finally, a design approach that takes into account the second-order effect is proposed to calculate the flexural capacity of the beams.
