Damage Estimation in Masonry Buildings Based on Excavation

Response of framed buildings to excavation-induced …

basis for estimating the potential building damage caused by tunnelling- and excavation-induced deformations. The procedure for building damage assessment, outlined by Mair et al. (1996), was based on deflection ratios and horizontal strains in the greenfield condition. This ignores the inherent stiffness in buildings and is conservative. To

Dynamic Modification and Damage Propagation of a Two

The progressive change of modal characteristics due to accumulated damage on an unreinforced masonry (URM) building is investigated. The stone URM building, submitted to five consecutive shakings, has been experimentally studied on the shaking table of EUCENTRE laboratory (Pavia, Italy). The dynamic characteristics of the test specimen are analytically estimated using …

A CASE STUDY OF DAMAGE ON MASONRY BUILDINGS …

The maximum strains obtained in the equivalent beam are used to determine thecategory of damage associated with masonry buildings (Burlandet al., 1977). This classification gives the description of the typical damage likely to occur in terms of type of affection, onset of cracking, cal crack width and typi ease of repair (see Appendix A).

In alternative approaches, building damage was estimated by empirical fragility curves developed from ground motion intensities and building damage statistics obtained in past damaging earthquakes [13,14]. The fragility function-based approach can estimate the number of damaged buildings expected from predicted ground motion intensities.

How to Calculate the Weight of a Load Before an Overhead Lift

Nov 29, 2018 · Here's how you would calculate the load weight of a block of aluminum that is 6 feet long, 3 feet wide, and 4 feet tall: Volume = Length x Width x Height. Volume = 6 feet x 3 feet x 4 feet. Volume = 72 cubic feet. Aluminum weighs 165 pounds per cubic foot (based on the numbers from the table above).
