Floods are globally recognised as a foremost and expensive hazard, cause extensive damage worldwide, affecting lives, property, and crops. Low lying terrain in most of the river basins of Sri Lanka and heavy rainfall in ...

Development of an economical level of service estimation model using gps data in a mixed traffic condition

Jayawardhana, SS; Perera, HLK [Conference-Abstract]

This research presents the development of an economical Level-of-Service (LOS) estimation model using GPS data in a mixed traffic condition, with a specific focus on defining clusters based on the categories within the ...

Study on buildings suitable to be constructed in hot, windy coastal regions

Dissanayake, DWTS; Baskaran, K [Conference-Abstract]

As Sri Lanka is a small island located in the Indian Ocean close to the equator, most of the built-up areas are close to the coastal belt and subjected to hot temperatures. Due to the diurnal temperature changes, coastal ...

Study on effectiveness of waterproofing in buildings during the design, construction, and maintenance phases of a structure

Priyashan, DMD; Fernando, PLN [Conference-Abstract]

Waterproofing is a critical aspect of building construction, ensuring longevity, durability, and structural integrity. There are several waterproofing methods used for buildings around the world. Among these, integral ...

Investigate the structural performance of pad footings with different ground improvements

Hondamuni, DC [Conference-Abstract]

When the footings are constructed on weaker soils, several structural enhancement techniques such as use of larger footings, micro piles, or different ground improvement techniques such as use of concrete cylinders and ...

Utilising bottom ash from waste-to-energy plants for sustainable cement block production

Tharsan, S; Baskaran, K [Conference-Abstract]

Bottom ash emerges as a by-product from the combustion of municipal solid waste in energy generation plants. The global predicament surrounding the management and disposal of bottom ash, an aftermath of waste-to-energy ...

Analysing the non-linear bending behaviour of ultra-thin woven composites at high curvatures

Tennakoon, TMH; Mallikarachchi, HMYC [Conference-Abstract]

Deep space missions require self-deployable structures built of ultra-thin materials which can be carried to space in a limited space. Therefore, a growing demand for ultra-thin woven composites has been identified in ...

Nature-inspired solutions for enhanced impact resistance of structures

Sajana, HMT; Fernando, PLN [Conference-Abstract]

High-velocity impact loads pose significant challenges due to their potential to generate dynamic responses in structures, which can cause severe damage. Structural engineers face an evolving challenge in designing ...

Numerical investigation on the effect of wind on façade fire propagation of a high-rise building in Sri Lanka

Lankadhikara, LRWMIM; Weerainghe, TGPL; Dananjaya, RMS [Conference-Abstract]

The façade is one of the most critical structural elements of a building. It serves as a barrier between the building’s inside and the outside environment. Beyond aesthetic appearance, the façade also plays a critical ...

Investigate the behaviour of glass balustrades under human impact loads

Wanigasooriya, TWMC; Damruwan, HGH [Conference-Abstract]

Glass balustrades are extensively used in various settings and are frequently subjected to different impact loads, including rigid or soft body impacts (human impacts). Ensuring the safe design and installation of glass ...

Effects of porosity and distresses in concrete on ultrasonic pulse velocity readings

Mayooran, M; Gamage, JCPH; Chandrathilaka, ERK [Conference-Abstract]

Ultrasonic Pulse Velocity (UPV) testing is a crucial non-destructive technique employed in the evaluation of concrete structures, providing insights into concrete properties and identifying potential damage. In this ...

Use of industrial waste sludge in concrete paving blocks

Basnayaka, BMI; Weerasinghe, TGPL [Conference-Abstract]

The interdependence of a nation's economic momentum with the dynamism of its manufacturing sector is evident. The era of rapid industrialisation brings with it an escalated output of waste. Addressing this surge, ...

Numerical modeling of char layer falling off in crosslaminated timber (clt)

Naveen, GWK; Weerasinghe, TGPL; Karannagodage, C; Kleinhenz, M [Conference-Abstract]
