Structural weakness Typically‚ 1970’s structures may require additional strengthening as part of the refurbishment works. Analysis of whether any loadbearing components have been removed should always be conducted so as to determine if bracing is supported and any other evidence of structural issues. Moisture Structures typically built in the 1970’s would have fewer weather tightness concerns. Although‚ weathertightness can occasionally be an issue if any fitted cladding has deteriorated over time

Footings are structural members used to support columns and walls and to transmit and distribute their loads to the soil in such a way that the load bearing capacity of the soil is not exceeded‚ excessive settlement‚ differential settlement‚or rotation are prevented and adequate safety against overturning or sliding is maintained. A foundation is the lowest and supporting layer of a structure. Foundations are generally divided into two categories: shallow foundations and deep foundations.

a. Social problems result from the ways in which society operates: connect this to the 3 sociological theories on how society is viewed to “operate”. There are many different opinions on what causes poverty. For instance‚ according to the structural functionalist perspective‚ poverty is caused by institutional breakdown. Examples of this are economic institutions that don’t provide enough jobs or pay‚ education institutions that don’t provide the members of society with enough education and skills

an RC slab can be poured over the roof‚ with no propping; the slab will only be say 110mm‚ 4 1/2"‚ and will weigh only about 180 kg/sqm. Such a slab will be completely bonded to the frame and will not be able to slip off‚ or collapse. If the building or structure is a normal single storey‚ then any normal portal frame or other steel framed building‚ if the design and construction is competently done‚ will be resistant to Earthquake loads.

volcanism. • The most obvious evidence of diastrophic movement can be seen where sedimentary rocks have been bent‚ broken or tilted. Types of Earth Movement: a. Uplift • Is the movement of the Earth wherein the crust rises. • Process in which structural highs in Earth’s crust are created (e.g. mountains). • The movement of tectonic plates and igneous plumes are two processes which may result in uplift. b. Subsidence • A sinking or setting of part of the Earth’s crust with respect to the surrounding

ADVANTAGES AND DISADVANTAGES OF PRESTRESSED CONCRETE ADVANTAGES : Use of high strength concrete and freedom from cracks‚ in prestressed members‚ contribute to improved durability under aggressive environmental conditions. The use of high strength concrete and high tensile steel in prestressed concrete members results in lighter and slender members than could be possible by using reinforced concrete and Mild steel as reinforcement. In prestressed concrete‚ steel is no longer required for
