TL;DR: In this article, an Fuzzy neural network (FNN) was used to predict wind loads on buildings on the basis of data obtained from model tests in wind tunnels, where simultaneous pressure measurements were made on a large flat roof model in a boundary layer wind tunnel, and parts of the wind tunnel test results were used as the training sets for the FNN to recognize the pressure distribution patterns.

TL;DR: In this paper, the eigenvalue equation for buckling of a non-uniform column with an arbitrary number of cracks, any kind of two end supports, and any number of rotational and translational spring supports at intermediate points can be conveniently determined from a second-order determinant based on the fundamental solutions and recurrence formula developed in this paper.
Abstract: The governing differential equation for buckling of a non-uniform column is expressed in the form of bending moment. The special solutions for 14 types of non-uniform columns are derived from the governing equation. Using a rotational spring and a hinge connection to describe the local flexibility induced by a crack in the column yields the eigenvalue equation for buckling. The main advantage of the proposed method is that the eigenvalue equation for buckling of a non-uniform column with an arbitrary number of cracks, any kind of two end supports, and an arbitrary number of rotational and translational spring supports at intermediate points can be conveniently determined from a second-order determinant based on the fundamental solutions and recurrence formula developed in this paper. As a consequence, the decrease in the determinant order as compared with previously developed procedures simplifies the analysis. A numerical example is given to illustrate the application of the proposed method and t...
