Effective stiffness of unreinforced brick masonry walls
Code design of Unreinforced Masonry (URM) buildings is based on elastic analysis, which requires as input parameter the effective stiffness of URM walls. Current approaches estimate the effective stiffness as fixed ratio of the gross sectional stiffness but comparisons with experimental results have shown that this does not yield satisfactory predictions. In this paper, a recently developed ana...
متن کاملApplication of Soft Computing Methods for the Estimation of Roadheader Performance from Schmidt Hammer Rebound Values
Estimation of roadheader performance is one of the main topics in determining the economics of underground excavation projects. The poor performance estimation of roadheader scan leads to costly contractual claims. In this paper, the application of soft computing methods for data analysis called adaptive neuro-fuzzy inference system- subtractive clustering method (ANFIS-SCM) and artificial neu...
متن کاملComparative evaluation of Schmidt hammer test procedures for prediction of rocks strength
Uniaxial compressive and Brazilian tensile strengths (UCS and BTS) of rocks are considered important properties in the design of most the geotechnical projects that interact with rock such as slope stability and underground excavation. Measuring UCS and BTS using standard laboratory tests are time consuming, tedious and expensive. Moreover, it requires a large number of well-prepared rock cores...
متن کاملSize Dependence of Strength and Fracture Properties of Brick Masonry
The test data on the size effect in the failure of masonry walls and some parts of the discussion of size effect are valuable. However, the theoretical description of the size effect is in my opinion invalid. The use of the "multifractal scaling law" proposed earlier by the senior author is unjustified, for the same reasons as it is for concrete structures. The reasons are explained in detail i...
متن کاملPeak and residual strengths of brick masonry spandrels
Unreinforced masonry (URM) walls comprise vertical piers and horizontal spandrels, which together form the lateral load resisting system. Whereas past research yielded significant advances in the understanding of the force–deformation characteristics of masonry piers, knowledge of the behaviour of masonry spandrels is lacking. This paper makes a contribution to our understanding of the seismic ...
