Introduction:
An online workshop has been conducted under supervision of Professor Youssef Rashed and the CUFE-BE team. This workshop has 2 main axes, the first one talks about the new developments of the boundary element method with the application of the BEM based software package (PLPAK)
The aim of this axe is to present both modern techniques developed in the boundary element method with its corresponding mesh-less version and the practical applications of the BEM via the PLPAK software package. The applications includes, tall buildings, non-linear soil-structure interaction, analysis and design of post-tensioned slabs, and accelerated solutions using GPU and multi-core methods. On the other hand, the second axes present the Preserving Egypt's Cultural Heritage from Earthquake Damage through Vibrating Barriers (ViBa).
The aim of this research study is to explore the use of the innovative ViBa (Vibrating Barriers) technique for preserving Egypt’s cultural heritage structures without taking measurements from any cultural heritage structure nor affecting it in any way. This research is based on computer modelling of the ViBa technique. Both the FEM and the BEM are used in computer modelling and simulations. The main goal of this research is to develop preservation guidelines against earthquake risk to be presented to the authorities in Egypt as documentation. The research idea will be implemented on the step pyramid and Cairo citadel.
This workshop will be presented by 14 lecturers from different universities and countries along duration of 3 days. It will be started at Tuesday 13-7-2021. The biography of the speakers is presented on the website as it is clear in figures 1,2,3,4 and 5. Each day of the workshop is divided to 7 slots and each slot is 30 minutes. Figure 8 contains an Excel sheet about the workshop details and the schedule of the 3 days of the workshop. There is a link on the web site for the registration of the workshop and for giving a feedback during the launching of the workshop also.

Speakers
Prof. John Katsikadelis
A graduate professor of Structural Analysis at the School of Civil Engineering at National Technical University of Athens (NTUA), Greece. He was educated at NTUA (diploma Civil Engineer and Dr. Eng. degree) and at the Polytechnic Institute of New York (MSc and PhD in Applied Mechanics). His research interests include static and dynamic analysis of structures. He is involved with BEM since 1975, when he derived the second boundary integral equation for the biharmonic equation in terms of the normal derivative used ever since in BEM for Plate Analysis. He continued his research in BEM for his PhD in Applied Mechanics developing the BEM for plates on elastic foundation. His published work includes 12 books and more than 260 papers in journals, conference proceedings and edited books, most of them dedicated to the development of BEM. His book “The Boundary Element Method - Theory and Applications”, Elsevier, 2002, has been translated in several languages (Japanese, Russian and Serbian). His contribution to BEM culminated with the introduction of the Analog Equation Method (AEM), which according to Prof. C. A. Brebbia is “the most general version of the principle of virtual work developments ever presented in science and engineering”. The AEM enables the application of BEM to static and dynamic problems described by linear and nonlinear differential equations of integer or fractional order using simple known fundamental solutions, rendering thus the BEM an efficient computational tool for engineering analysis and design. His book “The Boundary Element Method for Plate Analysis”, Academic Press- Elsevier, 2014, with a foreword by Prof. C. A. Brebbia, illustrates this method. Prof. Katsikadelis has accumulated many honors and distinctions in his intensive career such as member of many Academies, honorary member of European Societies of Mechanics, member of the editorial board of several prestigious journals, among the International Journal of Engineering Analysis with Boundary Elements.
