Museums are one of the important means of attracting many visitors to them, and the more enjoyable the experience is, the greater the demand for them and their importance in conservation on their heritage pieces of cultural, artistic and historical value. This value gains increasing importance when integrated into the digital system. Research problem appears in lack of using digital technology to enhance museums, attracting visitors, and improving their experience, while conserving artistic and historical value, Also, methods of current display in old Egyptian museums are insufficient to effectively convey information and participate visitors. This research aims to explore new ways through digital technologies in developing museums, their interaction with their visitors to achieve sustainability, and enhance the user experience during visiting museums and make them more attractive and interactive knowledge exchange as well. The research follows the deductive analytical theoretical approach. It focuses on concept of digital museums, how using digital technologies in developing museum display in international experiences museums to benefit from them in Egyptian museums, and using of digital technologies Alexandria Library (AL) Museums - Alexandria City as a case study. Finally, the research propose mechanism for using digital technologies in developing museums. The research ends with results and discussion then a presentation of the most important conclusions, which can be summarized in that possibility of benefiting from digital technologies developments in developing museums display. The study recommends by using of modern digital technologies in developing museums, especially heritage ones, and for their continuity for future generations.

Numerical analysis is conducted to investigate the settlement and tilting behavior of a group of piles adjacent to an excavation in saturated sand by using PLAXIS 3D finite element software. Moreover, the analysis aims to gain a better understanding of the load transfer mechanisms of the piled foundations due to an adjacent excavation. The influences of excavation depth, pile group location from excavation, initial working load, supporting system stiffness, and stiffness of piles and cap are investigated. As excavation proceeds, settlement and tilting of the adjacent buildings can be observed at different stages of excavation. The pile group settles to its maximum amount when the rear piles are in the position of maximum greenfield ground surface settlement. The settlement of the pile group can be significantly reduced by increasing the supporting system stiffness and decreasing the pile cap's applied load. The pile group settlement due to the excavation increases from 2.99 to 3.80% of the pile diameter when the ratio of applied load to ultimate load-carrying capacity of the pile group increases from 0.25 to 0.5. A clearly noticeable tilting can be observed when the pile group is located near the excavation. By increasing the pile cap's applied load and supporting system stiffness, the pile group tilting decreases. The settlement and tilting of the pile group are almost insensitive to the modulus of elasticity of the concrete piles and the cap. Loads are transferred between the toe and the shaft of the piles at different excavation stages.

The use of hybrid reinforcement (Stee/GFRP) system was proposed in the present study as a vital solution for overcoming corrosion problem with a proper energy dissipation capacity. This study also presents a preliminary step toward developing a force reduction factor for concrete columns reinforced with hybrid reinforcement. Nonlinear finite-element analysis (FEA) was used as a tool to achieve the research target. A novel FEA model for RC columns that captures the behavior of concrete columns solely reinforced with steel or GFRP bars and have been previously published by the first author, was first summarized. The study was then extended to test the effect of using hybrid reinforcement in terms of crack patterns, failure modes and load–lateral displacement hysteretic response. The force reduction for the hybrid RC specimen was also estimated. The reported test results clearly revealed that properly detailed hybrid RC columns have a recoverable and self-centering ability. The hybrid RC column sufficiently achieved the maximum drift meeting the limitation of most building codes. Acceptable levels of energy dissipation accompanied by relatively small residual forces, compared to the steel-reinforced column, were observed. The force reduction factor was suggested to be taken 2.5 for hybrid RC columns.
