Design Example: Sustainability in Concrete Building

Design Example: Sustainability in Concrete Building

As the construction industry moves towards more eco-friendly practices, concrete's adaptability and its ability to incorporate sustainable features make it a key material in the drive towards greener building solutions.
There are multiple approaches to achieve sustainability in a commercial concrete building. For instance, construct a concrete parking area under the building, utilizing pervious concrete paver blocks in open areas to facilitate rainwater collection through an underground cistern.

Design Example: Managing Concrete Workability

Design Example: Managing Concrete Workability

This example deals with managing the workability of concrete for a raft foundation project under hot weather conditions. Workability is crucial for ensuring the concrete is easy to place, compact, and finish. In this scenario, a slump test — a common method to measure the workability of fresh concrete — initially indicated low workability. This was attributed to the rapid water loss from the concrete mix, exacerbated by the high temperatures causing the course aggregates to heat up.
To address...

Design Example: Dimensioning of Concrete Masonry Construction

Design Example: Dimensioning of Concrete Masonry Construction

For the construction of a storeroom using concrete masonry units, it's essential to align the dimensions of the structure with the actual sizes of the blocks and the intended mortar joints. On the site in question, there's a stockpile of concrete masonry blocks with a nominal size of eight by eight by sixteen inches, which are to be used in the construction of the storeroom.
The site engineer has laid out a plan for the storeroom with external dimensions of twelve feet in length and eight feet...

Design Consideration

Design Consideration

Designing a structure involves a series of considerations, primarily the material's ultimate strength, calculated through tests that measure changes under increased force until the material reaches its breaking point or limit. The ultimate load, where the material breaks, is divided by its original cross-sectional area, resulting in the ultimate normal stress or strength. The ultimate shearing stress is another significant factor taken into account.
The factor of safety is another key aspect...

Design Example: Analyzing Capacity Contours for Flood Risk Assessment

Design Example: Analyzing Capacity Contours for Flood Risk Assessment

Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...

Composite Masonry Walls

Composite Masonry Walls

Composite masonry walls combine multiple wythes of the same or different masonry materials to create a unified structure. These walls feature wythes that are bonded together either through mortar-filled collar joints, grouted spaces, or more commonly, with rigid metal ties and reinforcements, with the use of masonry header units being rare. Metal ties are preferred because they effectively minimize water penetration, as these walls primarily absorb moisture and then release it into the...

Area of Science:

Environmental Science
Architecture
Sustainable Design

Background:

Construction, demolition, and excavation waste in England reached 91 million tonnes in 2003.
Current waste minimization strategies primarily focus on on-site management and recycling, neglecting design's impact.
Architects are recognized as key influencers in reducing waste through design-out strategies.

Purpose of the Study:

To examine architects' approaches to construction waste minimization.
To investigate the origins of construction waste.
To identify waste minimization design practices, responsibilities, and barriers within the UK architectural profession.

Main Methods:

Review of previous studies on architects' roles in waste minimization.
A postal questionnaire survey distributed to UK architects.
Analysis of architects' perceptions on waste origins and design practices.

Main Results:

Waste management is not a priority during the architectural design process.
Architects often perceive waste generation as primarily a site operation issue, underestimating design's contribution (up to one-third of waste).
Barriers to proactive waste reduction include client disinterest, prevailing attitudes towards minimization, and inadequate training.

Conclusions:

Design decisions significantly contribute to construction waste, yet this is often overlooked by architects.
A shift in focus towards integrating waste minimization early in the design phase is crucial.
Addressing client attitudes, professional training, and fostering interest are essential for sustainable waste reduction in construction.
