Least-thickness symmetric circular masonry arch of maximum horizontal thrust

The Behaviour of Skewed Masonry Arch Bridges

Surface Interaction Model for Great Thickness Masonry

At present, many of the historic masonry structures in the most important seismic zone of Argentina present damages due to the actions to which they have been subjected. Therefore, it is necessary to study the behavior of walls of ceramic masonry of great thickness. This work presents the comparison between the results obtained from the numerical simulation of ceramic masonry walls subjected to...

A Parametric Study: Frame Analysis Method for Masonry Arch Bridges

The predictability of masonry arch bridges and their behaviour is widely considered doubtful due to the lack of knowledge about the conditions of a given masonry arch bridge. The assessment methods for masonry arch bridges are MEXE, ARCHIE, RING and Frame Analysis Method. The material properties of the masonry and fill material are extremely difficult to determine accurately. Consequently, it i...

Sensitivity Analysis and Parameter Identification on historical Masonry Arch Bridges

Close to reality computation of the serviceability and load-carrying capacity of old masonry arch bridges for rising live loads is a current problem. In Germany many of such roadand railway bridges exist. Some of the most important features for applicable numerical evaluation of masonry arch bridges are a realistic structural model (very often three dimensional models are necessary), the consid...

Horizontal Symmetric Model

We consider an SU(2)L × SU(2)R × U(1)B−L × SU(3) L H gauge model with natural flavour conservation in the Higgs sector, in which CP-violation occurs due to the horizontal interactions only. We calculate the CP-violating observables ǫ and ǫ′ of the neutral kaon sector and dn, the electric dipole moment of the neutron. The regions of the parameter space which yield a value of ǫ that is in agreeme...
