Structural engineering is a field of engineering dealing with the analysis and design of structures that support or resist loads. Structural engineering is usually considered a specialty within civil engineering, but it can also be studied in its own right.
Calculation of Building Loads The loads on building, may be a residential or any type of structure, are mainly classified into vertical and horizontal loads. The vertical loads are the dead and live load. The horizontal loads are the earthquake and the wind loads. This is the general classification of loads. In this article, some … Read more
Introduction Monolithic Dome is thin wall reinforced concrete shell structure. The structure provides safe shelter for the people in the area with hurricanes and earthquakes. This technique is an effective alternative to conventional methods. A Monolithic Dome is a structure cast in a one-piece form. A curve rotated about a central axis to form a … Read more
Tunnel Boring Machine (TBM) A TBM is a massive set of complex equipment assembled together to excavate a tunnel, often called as “Mole”. Major components of this Tunnel Boring Machine includes Cutter head, with cutting discs/tools and Muck buckets to carry and dispose excavated muck Power supply Systems Cutter head rotation & thrust Bracing system … Read more
Base Isolation System: An Outline on Principles, Types, Advantages & Applications What is Base isolation? Base isolation is a state-of-the-art method in which the structure (superstructure) is separated from the base (foundation or substructure) by introducing a suspension system between the base and the main structure. In context of seismic design of structures, base … Read more
Things You didn’t Know about Chaotianmen Bridge – World Record Steel Arch Bridge The Chaotianmen Bridge is built across the Yangtze River, Chongqing, China. The total length of the main bridge and both west and east approaches is 1741 m, the span layout of Yangtze River Bridge is 190 + 552 + 190 m to … Read more
Dynamic Analysis Methods for Seismic Bridge Design Depending on the seismic zone, geometry, and importance of the bridge, the following analysis methods may be used for seismic bridge design: The single-mode method (single-mode spectral and uniform-load analysis) assumes that seismic load can be considered as an equivalent static horizontal force applied to an individual frame … Read more
Principles of statics Principles of statics consists of the study of structures that are at rest under static equilibrium conditions. To ensure equilibrium, the forces acting on a structure must balance, net torque acting on the structure should be zero. The static analysis methods provide the means to analyze and determine both internal and external … Read more
Flat Plate The flat plate is a two-way reinforced concrete framing system utilizing a slab of uniform thickness, the simplest of structural shapes. Flat Plate System Introduction A flat plate is a one- or two-way system usually supported directly on columns or load bearing walls. It is one of the most common forms of construction … Read more
Buckling of Columns – Euler Theory for Elastic Buckling BUCKLING – Loss of stability –Axial loads cause lateral deformations (bending-like deformations) Buckling of Columns is a form of deformation as a result of axial- compression forces. This leads to bending of the column, due to the instability of the column. This mode of failure is … Read more
