Civil protection structure

Waterproofing, whether it has to do with protecting civil engineering structures or roofs or terraces. Poured asphalt, often placed in layers with kraft paper, oxidized bitumen or modified bitumen can be used, generally with copolymer. The modified bitumen are used for the making prefabricated multi-layer waterproofing composites. [Pg.289]

For structures with a very long lifetime requirement such as tunnels and other major civil engineering structures it is possible to carry out calculations to predict the likely time to initiation of corrosion for different concrete cover, mix designs and protective system (see Chapter 9). The chloride concentration at the surface can be predicted or estimated from structures in similar conditions. If special concrete mixes are being designed then the diffusion constant can be calculated according to the equations in Chapter 9 and the time for the corrosion threshold to reach the steel can be calculated. Calculating the consequences of reduced cover is also possible. [Pg.247]

The high level of trust in emergency and civil protection institutions and the overall knowledge of meteorological and civil protection alerts showed by respondents are indicators of a general concern for hazards and their possible consequences, and do establish a sohd basis for the implementation of a structural security culture that promote civic epistemologies related to risk and risk governance. [Pg.1199]

Seismic bearings for protection of buildings, bridges and other civil engineering structures. [Pg.51]

Armourstone refers to large blocks of rock that are used to protect civil engineering structures. Large blocks of rock, which may be single-size or. more frequently, widely graded (rip-rap), are used to protect the upstream face of dams against wave action. They are also used in the construction of river training schemes, in river bank and bed protection... [Pg.289]

After the earthquake in the Abruzzo region on April 6th, 2009, the Department for Civil Protection and the ReLUIS consortium issued a draft of guidelines with the purpose of providing support in the design of the structures impacted by the seismic event, containing the terms and criteria for the definition of these projects. [Pg.56]

The issue with the strengthening of beam-column joints is extensively described in the draft of the Guidelines for Reparation and Strengthening of Structural Elements, Curtain Walls and Partitions edited by the Department of Civil Protection and by the ReLUIS consortium in August 2009 that highlights that the majority of failures of joints and of the requests for ductility in columns is usually localized in the exterior joints and columns, particularly those in the comers, for the following reasons ... [Pg.82]

Cement coatings and linings are used in civil engineering to protect structures and pipes made of steel. The coatings are often applied by use of a spray gun. They harden by hydration of the cement. [Pg.531]

Passive energy dissipation systems (e g. viscous dampers, metallic dampers, friction dampers etc) have been used extensively for the protection of civil engineering structures against strong earthquakes, therefore in this chapter are shown and compared three practical search methods for the optimal placement and design of dampers. They are called ... [Pg.19]

Risk assessment The estimation of seismic risk is the fundamental step in risk management and decision-making for risk mitigation. Risk assessment refers to the probable future losses (physical, performance, economic, social) not only due to structural damages but also considering the business interruption or interdependencies of lifelines. Lifeline companies and civil protection authorities are asked to determine how to best allocate the limited resources for risk reduction measures (actions 2, 3, and 4) based on the results of seismic risk analyses for their facihties and the... [Pg.853]

Change of use of an existing structure that increases the overall risk in case of an earthquake (e.g., an office building which now headquarters strategic departments of civil protection or an industrial building which now contains hazardous substances) ... [Pg.1850]

Anodic alumina oxides find steadily growing application in various spheres of technology. Traditionally, they are most popular in civil industrial engineering for producing protective and decorative surface finish in panels and different objects. These applications are well reviewed in the literature.321 Anodic alumina is also widely used in the aircraft and aerospace industry for adhesive bonding of aluminum structures,322-324 composite materials, etc. [Pg.487]

The impacts of TSCA, such as those on two specific exemplary industries, surface coating polymers and metal-cutting fluids, by S.Oslosky and H.Fribush, respectively, are implied but actually not explicit within TSCA. Consider the required assessment of risks, the need for test-data describing effects on health and the environment, aside from plant inspections, subpoenas, prohibited acts, penalties for prohibited acts, enforcement and seizure, judicial review, citizens civil actions and petitions, and employee protection provisions in the Act. Thus, it s inevitable that the alert manufacturer will adjust his product research, development and selection processes to identify and use substances with reduced risk to health and the environment wherever possible. As structure-(biological)-activity relationships become more reliable, the alert... [Pg.4]

Nature s use of calcium has been replicated by human civilizations, which have quarried limestone and constructed buildings that have lasted thousands of years. The Romans manufactured concrete and mortar but did not realize that they were in effect mining calcium from the kingdom. Without this product of the region of the Western Desert, not only would there be no permanent structures in civilized societies but organisms would never have developed weapons of attack (no teeth or tusks) or protection in the form of shells. [Pg.15]
