Stiffnesses of Nonprismatic Member
Publication: Journal of Structural Engineering
Volume 114, Issue 2
Abstract
The purpose of this note is to demonstrate a method for generating stiffness matrices for nonprismatic members which can be included in any computer program for solving rigid frame problems. In creating member stiffnesses, the conjugate beam method has been employed. For generalization, numerical methods are used for solving the conjugate beams, because different types of nonprismatic members have different section properties, and therefore cannot be expressed with a single mathematical function. For the convenience of computer programmers, the writers included the fixed-end moments and shears due to concentrated loads and uniform loads.
