WebbFor box girder bridges, the depth of the box girder usually varies in the longitudinal direction; the bottom flange is usually shaped as a cylindrical shell with variable radii. In order to analyze this type of structure, the vertical web strip with variable depth and the cylindrical shell strip with variable radii are developed. This makes the finite strip … WebbInterpolation within the elements is achieved through shape functions, which is the topic of this chapter. 4.1 Linear shape functions for bar elements Let us isolate a bar element …

WebbShape functions are said to have compact support, i.e. they are nonzero only over the elements which touch the node with which they are associated, everywhere else they are … WebbWe employ the concept of the reference element which seems (in the authors’ opinion) more suitable for the implementation. Moreover, we include a description of the necessary data structures. In Section 1.3 we present a construction of the basis functions based on two possible sets of shape functions, the Lagrangian and the Lobatto shape ...
WebbThe purpose of the isoparametric formulation is to create shape functions that would ensure the compatibility of the displacement between neighboring elements while maintaining the requirements for shape functions mentioned in the previous section.
