Special Issue Information

Dear Colleagues,

You are kindly invited to contribute to the Special Issue dedicated to the memory of the late professor Marcello Pignataro, who passed away on August 24, 2022. Professor Pignataro was one of the first of his time in Italy to attend a master in the United States, becoming close with the late professor W. T. Koiter, the father of the contemporary theory of elastic stability, of whom he considered himself a pupil. In his lifelong career at the university of Rome “La Sapienza”, professor Pignataro was the founder of the local school on stability investigations, inspiring the research interests and curiosity of his younger colleagues, who followed his path —among them, we may note Raffaele Casciaro, Nicola Rizzi, Angelo Luongo, and Giuseppe Ruta. Thus, this Special Issue is devoted to all researchers who wish to propose their studies in the fields of static and dynamic structural stability.

Welcome papers will be those that explore areas falling within the scope of CivilEng, namely: (i) static stability of civil structures, such as tall buildings, towers, reservoirs, and so on; (ii) static stability of structural elements under non-trivial loadings or in the presence of damage; (iii) dynamic stability of structures, for instance under nonconservative actions, e.g., in conjunction with fluid interaction or parametric excitation; (iv) multi-stable structural elements and their applications in civil engineering; (v) and bifurcation phenomena in innovative materials. Those are just instances of the possible topics that can explored, but of course any contribution in the field of stability will also be considered.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. CivilEng is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1200 CHF (Swiss Francs).

The stick–slip phenomenon is a jerking motion that can occur while two objects slide over each other with friction. There are several situations in which this phenomenon can be observed: between the slabs of the friction dampers used to mitigate vibrations in buildings, as well as between the components of the base isolation systems used for seismic protection. The systems of this kind are usually designed to work in a smooth and flawless manner, but under particular conditions undesired jerking motions may develop, yielding complex dynamic behavior even when only a few degrees of freedom are involved. A simplified approach to the problems of this kind leads to the mechanical model of a rigid block connected elastically to a rigid support and at the same time with friction to a second rigid support, both the supports having a prescribed motion. Despite the apparent simplicity of this model, it is very useful for studying important features of the non-linear dynamics of many physical systems. In this work, after a suitable formulation of the problem, the equations of motion are solved analytically in the sticking and sliding phases, and the influence of the main parameters of the system on its dynamics and limit cycles is investigated and discussed.
