there are several methods for analysing the behaviour of underground structures under different loading conditions. most of these methods have many simplifications; therefore, in some cases, the results are too conservative and a very high safety factor, usually of more than 2 is needed. on the other hand, for stability analysis and the designing of support systems, these methods consider segme...

Recently, different com plex lightweight structures are designed to save printing material, while satisfying specific demands on physical and geometrical properties. However, most structures need additional interior support structures to help print, which not only damage the physical properties of the objects but also consume additional material, time, and energy. To handle the above problem, a...

We introduce another item in the already large list of techniques for attribute evaluation. Our algorithm consists in computing an attributes by reduction to normal form using a transducer operating on tree encodings of a cyclic representation of zippers. A zipper is a data structure introduced by Gérard Huet for representing a subtree together with its context, i.e. it is a tree with a focus t...

the objective of this review to be submitted in two independent parts, for steel frames and for rc frames, is to compare their structural performance with respect to the proposed n2-method, and so also of the consequent convenience of using pushover methodology for the seismic analysis of these structures. a preliminary investigation is presented on a pushover analysis used for the seismic perf...
