Structural Analysis of Retaining Walls

Structural Analysis of Retaining Walls

Retaining structures or a retaining wall is any constructed wall that holds back soil a liquid or other materials where there is an abrupt change in elevation. Retaining walls have been used for thousands of years, in the construction of terraced fields on a steep slope, or a railway through a hillside, a retaining wall is used in some form or another.

Structural Design of Timber Posts to EC 5

Structural Design of Timber Posts to EC 5

Timber posts are vertical elements, when utilized in any timber frame are principally subjected to both axial compressive actions and bending moments along one or both axes. In other words, a timber post is the equivalent of a column, but in this case the term ‘post’ refers to timber or steel.

Axial Shortening in Tall Buildings

Axial Shortening in Tall Buildings

This article discusses axial shortening and its causes, how they can be predicted, evaluated and mitigated. It would explain the measures structural engineers and building contractors may employ to counter its effect. It would also make references to the current codes of practices were necessary.

Structural Design Of Timber Joist to EC 5

Structural Design Of Timber Joist to EC 5

Timber joists are one of the most basic structural elements found in many timber frame construction. They are closely spaced timber beams (typically in the range of (450-900mm) used to support a suspended ceiling, timber flooring or sheathings. In this article, we shall discuss the design procedure of timber joist. All advice given will be based on the guidance and recommendations of BS EN 1993-1-1:2004 Eurocode 5 Design of Timber Structures- Part 1-1: General common rules of buildings.

Structural Drawing Connotations and Interpretation

Structural Drawing Connotations and Interpretation

The reading and interpretation of structural engineering drawings is a much-underrated skill. A skill that is often not taught but learnt through frequent exposure to structural engineering contents and a drive to fully understand them. In simple form, a structural drawing can be defined as any drawing consisting of plans or set of plans and details explicitly showing how a building or structure will be constructed

Design of Steel Trusses to Eurocode 3

Design of Steel Trusses to Eurocode 3

Many problems of long spanning in structural engineering can be resolved through the use of steel trusses. These days, long span structures are very popular– from sport arena roofs to auditorium galleries, airport terminals, railway stations etc….

Geotechnical Design of Spread Foundations  to EC 7

Geotechnical Design of Spread Foundations to EC 7

A properly designed foundation must deliver these loads to the soil without overstressing the soil which could otherwise cause excessive settlement or shear failure of the bearing soil. In-order to avoid overstressing the soil geotechnical engineers and structural engineers must determine the bearing capacity of the soil upon which the structure is to be founded.

The Citicorp Centre Tower: Almost a Tragedy

The Citicorp Centre Tower: Almost a Tragedy

Somewhere in Manhattan, a team of carpenters, welders and labourers were secretly working through the night, retrofitting steel connections under the directive of one of America’s finest Highrise structural designer, in a race to salvage the world’s 7th Tallest building. The skyscraper was meant to be a structural masterpiece but instead was poised to become one of the greatest engineering disasters of all time. Hurricane season was approaching and even a moderate storm would put the lives of over 200k people at risk

Introduction to Steel Portal Frame Structures

Introduction to Steel Portal Frame Structures

Steel portal frames are the most common and cost-effective structural solutions for single-storey buildings with gable-pitched roofs. In fact, about 50% of the steelwork in the U.K is used up in the construction of single-storey buildings, of which portal frames form the greater part…

Construction of Cast-in-place Concrete Bridges

Construction of Cast-in-place Concrete Bridges

Whilst construction methodology tends not to be an issue in many buildings, the same cannot be said for bridges. Nearly all bridges cannot and should not be designed without good knowledge of its temporary stages and construction methodology4. In most cases it is the construction method that determines the design. In selecting the best scheme, a bridge designer would aim to select a construction method and a bridge layout as they are basically entwined.
