Earth plasters have been used as a protective coating for buildings but, due to their low strength and low resistance to weather conditions, they have been abandoned for more resistant materials which in return lack vapour permeability. Earth plasters have usually a high moisture sorption rate, and their water vapour permeability is high, allowing the transfer of humidity through the material. These properties make them an interesting material for controlling vapour movement in humid rooms. Improving their strength can be done by adding aggregates and/or fibres, but the real impact of using one type or another of fibres or aggregate is unknown. This research aims to understand the consequence of the choice of fibre or sand in the improvement of strength of plasters and the conservation of the plaster hygro-thermal properties. Properties of plasters using alternative fibres or aggregates such as wool, cow hair, pine needles, sand aimed for concrete mixes, or not properly graded sand have been compared to plasters made more traditionally with chaff fibres and masonary sand.

Ultimate load capacity of optimally designed cellular beams Erdal, Ferhat; Tokdemir, Turgut; Saka, M. Polat; Department of Engineering Sciences (2011) Cellular beams became increasingly popular as an efficient structural form in steel construction since their introduction. Their sophisticated design and profiling process provides greater flexibility in beam proportioning for strength, depth, size and location of circular holes. The purpose of manufacturing these beams is to increase overall beam depth, the moment of inertia and section modulus, which results in greater strength and rigidity. Cellular beams are used as primary or secondary floor beams in o...
Radiation effect studies on partially crystalline bulk amorphous Fe-based metallic glass Kiceci, Pelin Uslu; Akdeniz, Mahmut Vedat; Demirköz, Melahat Bilge; Mehrabov, Amdulla (2022-02-01) The selection of appropriate materials for radiation environments is critical due to the harsh and aggressive conditions found in such environments, which are liable to degrade material properties. Therefore, durability of materials should be tested before being deployed. In this respect, proton tests are required for the materials to be used in the space environment because dominant galactic cosmic rays mostly comprised high energy protons. Bulk metallic glasses are candidate for space environment due to t...
Tunable optical properties of Dy3+; Eu3+ doped, Dy3+/ Bi3+; Dy3+ /Ce3+; Dy3+/ Eu3+; Tb3+ /Ce3+ codoped LaBO3 Abacı, Özde Ceren; Yılmaz, Ayşen; Esentürk, Okan; Department of Chemistry (2017) In recent years, light emitting materials especially trivalent rare earth ions (RE3+) doped inorganic borate phosphors have attracted much attention due to their useful applications in several fields, which include flat panel displays, white light emitting diodes (WLEDs), solar cells, thermoluminescence dosimeters. In this research, single phase Dy3+; Eu3+ doped Dy3+/ Bi3+; Dy3+/ Ce3+; Dy3+/ Eu3+; Tb3+/ Ce3+ codoped lanthanum orthoborate phosphors were prepared by microwave assisted solid state synthesis me...
Seismic Behaviour of RC Frames Infilled with Different Techniques Demirel, İsmail Ozan; Yakut, Ahmet; Binici, Barış (2017-01-09) Besides their primary implementation as heat isolation and partitioning off the living space, infill walls have great potential to influence building response during seismic excitation. Affecting the infilled RC building stock of Turkey, Mw 7.4 Kocaeli (1999) and Mw=7.1 Van (2011) earthquakes have shown that “non-structural” infill walls might be very critical for vertical stability of buildings under severe earthquakes and their performance is important in determination of global building performance espec...
Creep effects on elastomeric and ball rubber bearings under sustained lateral loads Natale, Andrea; Del Vecchio, Ciro; Di Ludovico, Marco; Caner, Alp; Naghshineh, Ali Karimzadeh; Jacak, Mary (2022-01-01) Base isolation applications are becoming popular in the seismic design of resilient structures and infrastructures. Even though the response of the bearings is widely studied under cyclic displacements, limited information is available for bearing response under sustained lateral loads. These types of loads can develop sustained lateral displacement in the bearing. During the holding time under sustained lateral displacement, the creep or stress relaxation may significantly change the properties of the bear...
