Column Shortening Analysis with Lumped Construction Sequences

Reduction of Differential Column Shortening in Tall Buildings

Effects of Column Shortening in Tall R.c. Buildings

In tall and very tall reinforced concrete buildings, long term column shortening due to creep and shrinkage affects the service life behavior of structural elements. Creep-induced column shortening depends on the axial stress level in the column cross sections and on its evolution in time. For this reason, the construction method and phases must be taken into account as a key factor in defining...

construction of vector fields with positive lyapunov exponents

in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...

A Construction of Arithmetic Progression-free Sequences and Its Analysis

We describe a particular greedy construction of an arithmetic progression-free sequence from a finite composition. We also give an analysis on the properties of the resulting sequence.
