Project Title: Investigation of out-of-plane response of infill walls with murfor reinforcement
Project Type: ITUNOVA AR-GE Projesi
Project Coordinator: Prof. Dr. Alper İlki

Abstract:  This project includes experimental studies planned to investigate the behavior of infill walls that are made of AAC infill units under in-plane and out-of-plane loads representing earthquake effects and to evaluate the benefits obtained from using joint reinforcement placed between masonry unit elements. Within the scope of the project, three full-scale specimens representing infill wall applications in reinforced concrete structures will be tested under in-plane and out-of-plane loads. One of the samples will represent the wall construction without joint reinforcement, and the other two samples will contain bed joint reinforcements with different materials and geometric properties. The same in-plane and out-of-plane loading protocol will be applied to all three samples, and improvements in joint reinforcement and infill wall performance and behavior will be investigated. It is planned to test the specimens in a laboratory environment, to continuously monitor and report the applied load, displacements and damage in various parts of the specimens.

İTÜ Faculty of Civil Engineering

It can be accepted that the history of ITU Civil Engineering Faculty was commenced in 1727 by the establishment of Humbarahane during the era of Damat İbrahim Paşa. However, this attempt was to no avail due to the martyrization of the studwents of this school by the Janissaries.


In 1734, during the grand viziership of Topal Osman Paşa, classes related to Civil Engineering was being taught in Hendesehane, which was founded in Üsküdar. Similarly, this school was also closed after three years due to the opposition of the Janissaries. The reasons of the tragedy that occured in Battle of Chesma, 1770 were inadequacy of the ships and the ignorance of the Ottoman Navy.


Although the Atlantic Map (1513) and the Map of Europe and the Mediterranean Sea (1523) by Piri Reis were the leading pieces of the era, Ottoman viziers were so ignorant that they claimed it was impossible for the Russian Baltic Fleet to reach the Mediterranean Sea assuming that there were no sea connection. With the proposal from Gazi Hasan Paşa and Baron de Tott, Mühendishane-i Bahri-i Humayun was established during the time of Sultan Mustafa III, aiming to train naval construction engineers. Since Ottoman Empire did not have any engineering schools at the time, military engineering classes were taught by French engineers beginning from 1784. French lecturers had to return to their country in 1788 with the increasing suppression from Austria and Russia, which were unwilling for the development and thriving of Ottoman Empire. In 1759, during the Grand Viziership of Koca Ragıp Paşa, Humbarahane was reopened in Karaağaç, Haliç (Golden Horn) and continued to teach even though it was incompetent. In 1792, Lağımcı Ocağı and Humbaracı Ocağı (Guild of Sappers) were established.
