WHAT IS STRUCTURAL ENGINEERING

Civil-Structural-Engineering-Consultant-Sydney

Structural engineering involves the analysis and design of all kinds of structures such as buildings, bridges, towers, tunnels, retaining walls and other infrastructure. Whereas civil engineering is more about designing infrastructure projects, such as roads, railways, dams and water systems. Structural engineering supports and maintains the built environment, where structures must be safe, serviceable, durable, aesthetically pleasing and economical.

It also involves applying maths and physics to traditional construction materials such as concrete, stone, steel, timber and glass and innovative engineering materials, including aluminium, polymers and carbon fibre.

Structural design decides the type of structure that is most suitable for a specific purpose, the materials to be used, the loads and other actions that the structure must sustain, and the arrangement, layout and dimensions of its various components.

Structural design involves precise calculations to ensure that:

  • the structure is sturdy
  • all parts have enough strength to handle the design loads
  • the structure will remain serviceable throughout its design life and able to perform the function intended

Lastly, structural design involves the meticulous preparation of drawings that will illustrate the engineering design to the contractors who will build the structure.

Structural analysis is an essential part of structural engineering. It involves the calculation of the response of the structure to the design loads and proposed deformations that it will be required to endure for decades to come. In structural engineering, deformation refers to when an object is temporarily or permanently altered due to force. These calculations allow structural engineers to choose the correct materials for the structure, and to ensure that it will be suitable for it’s purpose.

FOOTINGS AND GROUND SLABS STRUCTURAL ENGINEERING SERVICES

Civil-Structural-Engineering-Consultant-Sydney

Conventional Raft Slab Design

Otherwise known as an engineered or floating slab, a raft slab involves reinforced concrete slab on ground that is strengthened with essential concrete beams in both directions. The type of soil the slab will be sitting on is dependant on the depth and spacing of the edge and stiffening beams.

Strip Footings Design

This is one of the most common footings used in Australia, consisting of a strip of reinforced concrete that supports an integral uniformly distributed load such as a wall.

Pad Footings Design

The most straight-forward and cost-effective foundation is pad footings, also known as isolated or spread footings, and are primarily used for shallow foundations in order to carry and spread concentrated loads from columns or pillars. They are created by digging holes into the ground, fitting the holes with a reinforcement cage, and finally pouring a concrete mix to ground level.

Waffle Pod Footings & Slabs Design

A waffle slab is made of reinforced concrete and is flat on top with a grid-like system of narrow strip footings on its bottom surface. It’s name derives from these narrow strip footings or ribs which are laid perpendicular to each other with equal depth.

Column Footings Design

One of the simplest types of foundations is a column footing. This footing is often a block of concrete on which the column sits so the weight placed on the column can be distributed through a larger area.

Load Bearing Pile Footings Design

These footings are commonly used for high-rise buildings or bridges. Load bearing pile footings become necessary if a home is being built on weak soil or uneven terrain. They are pushed into the ground until a solid base can be found so that structures can be supported on top of it.

Bored Pier Footings Design

Bored pier footings come into play in wet and coastal areas where footings and slabs require further support. After they are filled with concrete, holes are drilled down to the level of good load bearing soil.

BEAMS AND COLUMNS STRUCTURAL ENGINEERING SERVICES

Designing beams in our structural engineering services

Beams

Beams are horizontal planks or rods that carry weight perpendicular to their direction (which is longitudinal). Beams are supported at both ends of installation and transfer loads from slab to column.

Location

These structural elements are used to support the weight of a building’s walls, ceilings and roofs. Their primary job is to spread the weight to a structure’s vertical load-bearing supports.

Design

Structural engineers must carefully design beams. The structural engineers at Engineering Sydney are educated and trained to calculate the loads acting on the beam and will choose an optimal beam size, shape and material to accommodate the forces and loads on the structure. Beam dimensions are also allocated according to the value of the internal forces located on them.

Material

The most common types of materials used to make beams include reinforced concrete, steel, grouted masonry and wood. Engineering Sydney’s structural engineers will select the material based on cost, geometry and fire rating, among other things.

Designing columns in our structural engineering services

Columns

Similar to beams, columns are used in structural support. Essentially, columns are vertical structures that transfer compressive loads. They support the floor or roof beams and the columns on the floors above; bottom floor columns must be strong enough to carry the full weight of each floor above it. They will transfer loads from the slab and beams to the foundations and soil beneath.

Location

For the most effective support, columns should be placed consistently on all floors (where possible), increasing the stability of the lowest set of columns.

Design

The structural engineers at Engineering Sydney must calculate the weight supported by the column before choosing an optimal design. Much like beams, column design relies on the load values extruding vertical forces. The effects of lateral forces due to wind and earthquakes must also be considered when deciding the size and dimensions of the column.

Material

The two primary materials used in modern column construction include:

1. Steel
2. Concrete

RETAINING WALLS STRUCTURAL ENGINEERING SERVICES

Civil-Structural-Engineering-Consultant-Sydney

What are retaining walls?

Retaining walls are structures used to provide stability and are commonly used to control soil banks. The structural engineering design of retaining walls varies across Australia. A geotechnical assessment is needed for all retaining walls, particularly those in clay sites. Drainage considerations are undertaken by the design structural engineering to ensure long term performance in retaining walls.

Types of retaining walls structural engineers design

Gabion Walls

A Gabion wall is a simple design and consists of rough cut stones or randomly collected stones of similar size, encased in a wire basket or mesh cage. They are easy to assemble on site, requiring only a specific stacking order to achieve stability and desired result. Gabion walls allow perfect sub soil drainage of the soil that is being retained.

In-Situ Concrete Walls

An engineer designed, concrete retaining wall can suit a variety of project needs. Since the construction of a concrete wall can be done by just about any builder. In-situ concrete walls may be cheaper to build except for their form work, and are more flexible, depending on the type of soil retaining required to be achieved.

Gravity Structures – Limestone Retaining Walls

The gravity wall depends upon its weight to retaining soil. Limestone retaining walls are a type of gravity walls commonly used in the Perth Region. The interlocking blocks that are used to construct the limestone retaining wall can be either natural blocks or reconstituted limestone blocks. Limestone retaining walls can be used in a wide range of applications and have a long durability. The type of retained soil is especially useful if required to supports imposed actions such as light vehicle surcharge loading.

Panel & Post Retaining Walls

Also known as concrete sleeper retainer walls, usually consist of concrete posts or steel beams cast into a concrete footings. The retaining is achieved with concrete panels inserted between reinforced concrete post or galvanised I beams. This type of retaining wall is easy and quick to install in sand sites. Also this type of retaining wall isn’t recommend within 1km from the ocean and to ensure durability, is it critical that the steel I-beams are galvanised.

Concrete Block Retaining Wall Systems

Retaining wall using concrete masonry blocks are straightforward to construct and since there is a wide range of colours and textures available, there are a range of options for retaining walls, planter boxes and feature walls. Concrete masonry retaining walls are typically constructed in Australia using 150 series blocks or 200 series blocks.

Structural engineering is often recommended for:

  • Retaining walls over 1m in height
  • Where the retaining wall is supporting a heavy load
  • Complex ground conditions
  • To fulfil council regulations i.e. Development Application, Works Orders, Emergency Works
