Response 2000Introduction:

It is a Sectional Analysis Program

used to Predict the Load Deformation response

of Reinforced/Prestressed concrete sections

subjected to combined actions of Shear, Moment and Axial load

Response 2000Introduction:Applicability of sectional analysis

Beam theory assumes that response of a section depends only on The section properties Values of applied stresses resultants

It ignores the details of how the forces are introduced in members

Response 2000Introduction:Applicability of sectional analysis

St. Venant's PrincipleB regions: Beam actionD regions: Arch action
