Abstract
Abstract This paper presents the first estimation for the mechanical properties and the mass density of the masonry of Al-Malwiya heritage minaret. Many approaches are investigated in order to estimate the modulus of elasticity, shear modulus, Poisson’s ratio, and the mass density for this historic masonry. The mechanical properties are estimated by using empirical formulas and analytical equations, while the mass density is estimated after carrying out experimental tests for the extracted samples of the historic mortar. The estimated properties showed relatively low values compared with the newly constructed masonries, but they were interpreted as reasonable for such a historic construction.
Highlights
Al-Malwiya is a historic minaret constructed in the city of Samarra, Iraq, during the reign of Al-Mutawakkil Ala-Allah, Abbasid Caliph, in 851 CE
Mass density is an essential physical property in computing the self-weight of the masonry which is a basic parameter in performing the structural analysis
The purpose of this study is to present the first estimation of the properties; modulus of elasticity, shear modulus, Poisson’s ratio, and the mass density, which are needed in structural analysis process for the masonry of Al-Malwiya
Summary
Al-Malwiya is a historic minaret constructed in the city of Samarra, Iraq, during the reign of Al-Mutawakkil Ala-Allah, Abbasid Caliph, in 851 CE. It has a spiral shape, as shown, and characterized by many values. There are many mechanical and physical properties that need to be found prior to investigating the structural behavior of the historic masonry buildings. The modulus of elasticity (Youngs modulus), the modulus of rigidity (shear modulus), and Poisson’s ratio are considered as the most important mechanical properties in structural analysis. Mass density is an essential physical property in computing the self-weight of the masonry which is a basic parameter in performing the structural analysis
