YLSE Company Profile

Sustainability & Efficiency While in the past the emphasis was on performance, time and cost, a new factor, sustainability, is now added to the decision-making process.

Environmentally Sustainable Design (ESD) endeavors to use design principles and strategies to reduce the environmental impacts caused by the construction and operation of buildings. (Palich et al.2011). Our responsibility to incorporate ESD in design and methodologies by aiming to improve structural effectiveness of a building.

Sustainability Environmental Impact A study has shown building construction in concrete structures contributes more than 50% of all anthropogenic greenhouse gas (GHG) emission globally and 50% to 62% of the global warming potential (GWP). Results indicate environmental efficiencies are achieved through both the material reduction of steel and concrete. Overall, up to 40.9% reduction in the global warming potential through the utilisation of post-tensioned construction methodology.

Social Impact During construction phase, designs requiring less of the same material lead to less disruption due to reduced pollution, trucking, traffic congestion and waste. In addition, a faster construction cycle can also reduce nuisances of construction sites. During the use phase, well-being depends largely on the conditions of interior space: concrete has clear benefits in lighting, acoustical and thermal comfort. Flat soffit improves on the architectural flexibility and contributes to the visual comfort.

Efficiency Cost Saving Estimation

per m2 *

The use of post-tensioning is able to significantly reduce the concrete volume up to 37% and steel mass up to 43% (D. Miller, et al. 2012), and further result in significant foundation material savings and reduced columns which indirectly reduce the overall financial cost. Fast construction time period is due to less material and less installation time and labor, and also due to stressing of the tendons consequently reflect the early stripping of formwork for quicker floor-to-floor cycle.

YLSE Company Profile

Realizing the Possibilities Post-tensioning provides a means to overcome the natural weakness of concrete in tension and to make better use of its strength in compression

In concrete structures, this is achieved by placing high-tensile steel tendons/cables in the element before casting. When the concrete reaches the desired strength, the tendons are pulled by special hydraulic jacks and held in tension using specially designed anchorages fixed at each end of the tendon.

Transfer Structures, Meta_City, Seri Kembangan

This provides compression at the edge of structural member that increases the strength of the concrete for resisting tension stresses. If tendons are appropriately curved to a certain profile, they will exert, in addition to compression at the perimeter, a beneficial upward set of forces that will counteract applied loads, relieving the structure from a portion of gravity effects.

Tension in unreinforced concrete produces cracking

In reinforced concrete rebar resists tension

Effects of curved post-tensioning tendon on the structure

YLSE Company Profile

Structural Design Post-tensioning tendons are virtually replaced in the slab by the set of forces they exert on it: compression along the perimeter, upward forces in the spans and downward forces over the supports.

YLSE is comprehensively qualified, proficient and experience in all post tensioning method and can guide in every aspect to the process including design, detailing, systematic equipment supply and installation. When an analysis is satisfactorily completed, structural detailing is carried out to show the layout and the dimensions of the slab, the distribution and profiles of the tendons, details of ordinary reinforcement, jacking forces and corresponding elongations in tendons due to stressing.
