An arch is a vertical curved structure that spans an elevated space and may or may not support the weight above it, or in case of a horizontal arch like an arch dam, the hydrostatic pressure against it.
In most structures in the UK the principal load bearing element is the masonry. Different types of masonry move at different rates, and sometimes in opposing directions ( Table 2 ). This can give rise to differential movement and distortion (see illustration of Herstmonceux Castle).
The paper presents an experimental research on the use of Textile Reinforced Mortar (TRM) for the strengthening of brick load bearing masonry walls subjected to eccentric loading.
Loadbearing mud brick wall construction requires particular attention to good bonding (avoiding continuous vertical joints) and ensuring stability by having returns on the walls that buttress them against sideways forces. Again, normal traditional masonry practice applies to the pattern in which bricks should be laid. It is possible to create arches, squinches and domes in mud brick; they have
Capozucca tested clay masonry shear walls with flanges under axial and lateral load. The flanges were then repaired with CFRP sheets. The lateral load was not applied dynamically, but nevertheless the finding was that the repairs were highly effective in increasing stiffness and ultimate loads.

In the paper, the usage of elastic and plastic approaches for the analysis and design of masonry arches is discussed, with respect to the application of a point load and a two-pinned arch. The results of a recent experimental program are also briefly reviewed and discussed in light of the results from numerical simulations using the finite element method. Finally, practical and conservative
One of the tallest buildings of loadbearing brickwork was the Monadnock building in Chicago (Burnham and Root, architects, 1890), which has walls 1800 thick at the base. These stylised floor plans give an indication of the relative thickness of the walls at the ground level (upper plan), and partway up.
Load traffic: Increasing loads on masonry arches may or may not be a structural issue; external signs like visible cracks in key positions such as in the spandrel walls or beneath the arch ring should provide warnings that the bridge should be assessed for its ability to handle actual traffic conditions, and eventually, retrofits should be instituted.
in the antechamber, the masonry of the load-bearing partition wall, separating the antechamber and the great hall, was started; as was the antechamber’s fireplace and the door leading into the aula. The masonry on the east gable was finished in readiness for the fitting of the first roof truss.

shallow arches supported by steel beams (jack arch system). Stone masonry walls, usually 400 to 600 mm thick, have adequate gravity load-bearing capacity, however their lateral load resistance is very low. As a result, these buildings are considered to be highly vulnerable to seismic effects. FIGURE 1: Typical Building 1.5 Typical Period of Practice for Buildings of This Construction Type How
