In the slab system, apply two-way reinforced concrete beam and slab system in No.1, 3, 4 units. Characteristic: • Long-span slab • The cantilever whose span surpass 5-meter, such as the cantilever in sky lobby at +11.00m level, should be applied beam system for post- tensioning prestress with bond.

Friction Factor - an overview | ScienceDirect Topics

The friction factor f is calculated by the expression: (13.80) f = [ cosϕ √0.18tanϕ + 0.36sinϕ + f0 / cos ϕ + 1 − cosϕ √3.8f90 / cos ϕ] − 0.5. where f0 and f90 are the limiting values of the friction factor with chevron wave patterns in phase at ϕ = 0° and ϕ = 90°, respectively, to be calculated by the expressions: •.

Cylinder-wall interference effects on finite-length wavy …

26/9/2013 · An experimental study was conducted on aspect-ratio of six finite-length wavy cylinders immersed within a Re D = 2,700 free-stream. Wavelengths of 2 and 4 diameters, as well as wave amplitude of 0.1, 0.2 and 0.3 diameters were used for a comprehensive investigation. Time-resolved particle-image velocimetry measurements and proper orthogonal decomposition analyses show that …

hydrogen can be produced from the effluent (Fulford, 2015). Steel reinforcement in concrete structures is primarily protected from corrosion by the alkalinity of concrete. Carbonation of the concrete mix reduces the alkalinity through the conversion of calcium

Blast Resistance - an overview | ScienceDirect Topics

Concrete is often used as its mass per unit cost is favourable, it has good fire resistance and with the steel reinforcement it has the ability to absorb large amounts of energy. Unfortunately, this solution can still be expensive, add considerable gravity loads to the foundations of a building and require a considerable period of time to install.
