The monitored settlement of the building was less than 3mm. There were 8 vertical and 20 horizontal electro- level beam sensors installed inside the Empress Place. Trigger values on groundwater levels, settlement markers and building evaluations should ensure that adverse. If monitoring during construction shows that settlement effects could be greater than the. Figure E14 prediction then. Installation (180 standpipe and 51 vibrating wire peizometers), in-situ hydraulic conductivity.

This paper presents a study of the influence of frame action on the response of buildings to deformations induced by deep excavations in soft clay. Using the finite element method, a building was modelled as a framed structure adjacent to a multi-propped excavation, firstly as a frame with continuous footings and then as a frame with individual footings. The geometry, location, and structural elements forming the frame models were varied to investigate the response of various frames. Using a structural analysis, parameters representing the stiffness of the frames in reducing deflection ratios and horizontal strains were derived. The influence of the frame action on the building stiffness can be quantified using the results from the finite element models. This makes it possible to estimate building modification factors from the relevant design charts so that induced deflection ratios and horizontal strains, caused by adjacent excavation and tunnelling activities, can be calculated.

A commemorative plaque, or simply plaque, or in other places referred to as a historical marker or historic plaque, is a plate of metal, ceramic, stone, wood, or other material, typically attached to a wall, stone, or other vertical surface, and bearing text or an image in relief, or both, to commemorate one or more persons,.

The approach gives a more realistic estimate of the tensile strains for assessing the potential damage caused to buildings. • Previous article in issue • Next article in issue.
