PCI eLearning Course T145: Shear Design—Development and Use of Modified Compression Field Theory
Description
This course presents the analysis of precast, prestressed concrete bridge members for vertical shear. The method taught is a truss analogy called the modified compression field theory in which the truss is composed of concrete “compression struts” and steel “tension ties.” It is one of two methods included in the LRFD Specifications for shear design. The other method is included in the following course, T150. Unlike flexural design, for which conditions at both service and strength limit states are evaluated, shear design is evaluated only for factored loads (strength)
After completing this course, the student will be able to:
Identify the mechanisms assumed in the Modified Compression Field Theory
Assess the influence of prestressing steel to the MCFT shear mechanism and resistance
Calculate the concrete contribution to shear resistance using MCFT
Calculate the web reinforcement contribution to shear resistance using MCFT
Calculate the total shear resistance using MCFT
