WET-CURING CONCRETE BLANKET

Wet Curing concrete Blanket is a reflective blanket particularly designed to be hydrated and inhibit moisture loss through the curing process of concrete.

 In modern Civil Engineering works such activities are on rise.

NEW HOME CONSTRUCTION - TIE BEAM

Rafters or Tie beam Rafter ties are considered to tie together the bottoms of opposing rafters on a roof, to resist the outer thrust where the roof meets the house ceiling and walls.

This helps keep walls from spreading due to the weight of the roof and anything on it, remarkably wet snow. In numerous or most homes, the ceiling joists also provide as the rafter ties. When the walls extend, the roof ridge will sag.

 A sagging ridge is one clue that the home may lack sufficient rafter ties. Rafter ties form the bottom chord of a simple triangular roof truss. They resist the out-thrust of a triangle that's trying to flatten under the roof's own weight or snow load.

They are positioned in the bottom one-third of the roof height. Rafter ties are constantly required unless the roof has a structural (self-supporting) ridge, or is built via engineered trusses. A lack of rafter ties is a grave structural issue in a conventionally framed roof.

NEW ECO-FRIENDLY BUILDING MATERIAL

A new eco-friendly building material that saves water and reduces the quantity of debris in a building construction is the precise material. This is the sort of sustainable and eco-friendly material that will assist creating cheap housing, green jobs, and fast benefits to the wider society.

This building material created in Brazil promises to lessen the impacts generated by the construction industry wide-reaching. The substitute is equivalent to mortar and reduces the production of use of water, slag, lime and sand to build walls.

The Mass dundun is glue used to fix the bricks and their application is additional sustainable than the mortar, since the product does not produce waste, keeps clean and combat works wasting many resources that would become rubble. Appropriate for sealing walls built with various materials – like brick, concrete, conventional ceramics and ecological brick, the product is a fluid that also promises to lessen the physical effort of workers retire and cement mixers.

MEDIA CITY FOOTBRIDGE,MANHATTAN

It's an asymmetric bobtail swing bridge, spanning across the Manchester Ship Canal. It's 83m long overall, with a 63m core span. To the north, it provides right to use to the new Media City development in Salford, the fresh home to several departments of the BBC. On the south bank, it presently connects to the Imperial War Museum North, but will ultimately link in to a new ITV studio development.

The bridge deck is supported by a harp-style cable-stay outline. The cables support one edge of the deck, and join to eight steel masts in a fan arrangement which I previously likened to a giant skeletal hand.

 I think possibly the design visualizations were a little unflattering, as now that I've seen the (nearly) finished structure, it is a much more attractive creature.

The unusual assemblage of masts arises from the formalism of the geometry. The cables create a harp arrangement in elevation (i.e. they are parallel when viewed from that angle), and are tangential in plan to the curved edge of the deck.

This creates geometry where the cables must be supported at eight detach positions in space, rather than from a single mast.

EFFECT OF SOFT STORY ON STRUCTURAL RESPONSE OF HIGH RISE BUILDINGS

Harsh structural damage suffered by numerous modern buildings during recent earthquakes illustrates the importance of avoiding abrupt changes in lateral stiffness and strength. Modern earthquakes that occurred have shown that a big number of existing reinforced concrete buildings are vulnerable to damage or even collapse during a strong earthquake.

While damage and collapse owing to soft story are frequently observed in buildings, they can also be developed in other types of structures. The lower level containing the concrete columns behaved as a soft story in that the columns were unable to give adequate shear resistance during the earthquake. 

Typically the most economical way of retrofitting such as a building is by adding proper bracing to soft stories. Also has been tired to investigate on adding of bracing in diverse arrangements to structure in order to reduce soft story effect on seismic response of building. 

It is lead to assess the susceptibility level of existing multi-storied buildings so that they can be retrofitted to have the minimum requirements. This will aid in minimizing the impending damages and catastrophes.
