Structural Design Criteria for Coastal Structures
Coastal structures are the structures that are constructed near to the coastal areas for different purposes. Different types of coastal structures are constructed under different circumstances but the criteria to be used for the selection and design of specific type of coastal structure must be authentic and comply with the standards.
Retrofitting Techniques for Existing Damaged Buildings
Primary aim of strengthening a structure is to increase its load bearing capacity with respect to its previous condition. Only those aspects related to flexure are discussed here. Established techniques which have been in use successfully for a number of years are recognized as follows: Over Slabbing Sprayed Concrete with Additional Reinforcement Steel Plate bonding External Prestressing
Retaining Wall - Definition and Types of Retaining Walls | Ret Wall
A retaining wall is a structure that retains (holds back) any material (usually earth) and prevents it from sliding or eroding away. It is designed so that to resist the material pressure of the material that it is holding back. An earth retaining structure can be considered to have the following types: Pre-stressed retaining wall Gravity Walls Reinforced Gravity Walls Concrete Cantilever retaining wall Counter-fort / Buttressed retaining wall Precast concrete retaining wall Prestressed retaining wall
Reinforcement Detailing in Concrete Structures
Detailing is as important as design since proper detailing of engineering designs is an essential link in the planning and engineering process as some of the most devastating connections. ACI Reinforcement location in non prismatic beam. ACI reinforcement detailing in cantilever beam. A design engineer's responsibility should include assuring the structural safety
Bonded Concrete Slab Post Tensioning
Post-tensioning is a method of reinforcing (strengthening) concrete or other materials with high-strength steel strands rebars, typically referred to as tendons. It has the following benefits as compared to unbonded post tensioning. Bonded post-tensioned concrete is the descriptive term for a method of applying compression after pouring concrete and the curing
Types of Supports for Loads | Roller, Hinge, Fixed
Roller supports are free to rotate and translate along the surface upon which the roller rests. The surface may be horizontal, vertical or slopped at any angle. Roller supports are commonly located at one end of long bridges in the form of bearing pads. This support allows bridge structure to expand and contract with temperature changes and without this expansion the forces
Frame Structures - Types of Frame Structures
Frame structures are the structures having the combination of beam, column and slab to resist the lateral and gravity loads. These structures are usually used to overcome the large moments developing due to the applied loading. Types of Frames: Frames structures can be differentiated into: 1. Rigid frame structure Which are further subdivided into:Pin ended, FixedDesign & Analysis of Slab in SAP2000

Bending moment at a point or at a section is the algebraic sum of Moments caused by forces action to the left or right of that point or section. Mathematically it can be written as
Analysis of Statically Indeterminate Beams by Force Method
While analyzing indeterminate structures, it is necessary to satisfy (force) equilibrium, (displacement) compatibility and force-displacement relationships. Force equilibrium is satisfied when the reactive forces hold the structure in stable equilibrium, as the structure is subjected to external loads. Displacement compatibility is satisfied when the various segments of the
Analysis & Design Report for Store & Generator Room
It is a frame structure single storey unit & includes areas for various purposes, such as transformer generator space. Ultimate Strength Design (USD) or Load and Resistance Factors Design (LRFD) method is used for structural design of all the components. The concrete used for all structural members should have a minimum 28 days cylinder crushing strength of 3,000 Psi.
