Concept of Retaining Walls Design -Calculation of Earth Pressure
There different types of retaining walls and their design concept starts with calculation of earth pressures. Earth pressure calculation on retaining walls depends on the depth, pore water pressure and surcharge on retaining walls. Cantilever Retaining Walls: (a) Cantilever retaining ...
DESIGN OF FOOTINGS – IS-456 RECOMMENDATIONS
DESIGN OF FOOTINGS – IS-456 RECOMMENDATIONS: GENERAL 1. In sloped or stepped footings, the effective cross – section in compression shall be limited by the area above the neutral plane, and the angle of slope or depth and location of ...
FREE-STANDING RETAINING WALL WITH TYPES
Free-standing retaining walls are constructed in an open excavation and the retained soil is backfilled after construction. Generally free-standing walls are only economically viable on sites where there is sufficient space to compact the sides of the excavation to stable ...
TENSION MEMBERS-CROSS-SECTION & BEHAVIOUR
Tension members are considered to be carrying only axial force. Tension members are subjected to uniform stress because their entire cross-section is used for carrying axial forces. Ties, suspenders of cable stayed and suspension bridges, building suspenders hung from central ...
Minimum Thickness of Concrete Slab, Beam, Column, Foundation
Minimum thickness of concrete slab, beam, column, foundation and other structural members is selected to meet the design requirements as per standard codes. Minimum thickness of concrete structural elements based on ACI 318-14, IRC 2009, IS 456 2000, and UBC ...
BLAST RESISTANT DESIGN OF STRUCTURES
Reinforced concrete can provide substantial protection from even extreme blast loading. The relatively large mass of concrete elements provides an inherent resistance to impulsive loads. Structural design considerations include sizing members to provide an expected degree of deformation and associated ...
ADVANTAGES OF PRE-ENGINEERED BUILDING SYSTEMS
There are many advantages of pre-engineered building systems, but all advantages lead to reduced construction time. Following are advantages of Pre-Engineered Building Systems: Reduced Construction Time: Due to the systems approach, the use of high strength steel, use of tapered ...
