Branch Switching from Coincident Bifurcation Points*

Autor: Markku Tuomala, Sami Pajunen

Publikováno v: Mechanics of Structures and Machines. 28:339-353

The definition of the solution set of a general non-linear structural problem depending on one external parameter is considered. Path-following techniques and singular point locating and identifying methods are reviewed, followed by so-called branch-

Testing and design of gravity-loaded steel purlins restrained by sheeting

Autor: Markku Tuomala, Markku Laine

Publikováno v: Journal of Constructional Steel Research. 49:129-138

This paper is prepared on the basis of a study, the aim of which was to determine experimentally the design parameters for a set of thin-walled steel purlins with C, Z, Zeta and Hat-cross-sections. In our study, special attention was paid to the stru

Static and dynamic analysis of space frames using simple Timoshenko type elements

Autor: Markku Tuomala, Reijo Kouhia

Publikováno v: Tampere University
International Journal for Numerical Methods in Engineering, 36(7), 1189-1221. Wiley

In this paper a finite element method for geometrically and materially non-linear analyses of space frames is described. Beams with both solid and thin-walled open cross-sections are considered. The equations of equilibrium are formulated using an up
