Earthquake Performance of free Standing four Legged Greenfield Towers

Gunathilaka, AMLN; Lewangamage, CS; Jayasinghe, MTR [Conference-Abstract]

Telecommunication/broadcasting towers play a vital role in telecommunication and broadcasting sectors by facilitating wireless data and signal transmissions. The failure of a tower especially under a disaster situation ...
Enhancement of engineering characteristics of peaty clay due to mixing with cement

Saputhantiri, DR; Kulathilaka, SAS [Conference-Abstract]

Thick layers of soft peaty clay encountered in recent infrastructure development projects in Sri Lanka had been improved mainly by different techniques of pre-consolidation. Alternatively, if peaty clay is mixed in situ ...
Liquefaction potential in Sri Lanka - preparing a liquefaction hazard map using geotechnical investigation data

Kumarasiri, HC; De Silva, LIN; Abayakoon, SBS

Soil Liquefaction is a process, where granular soils below the ground water table temporarily lose their strength due to cyclic loading created by an earthquake. Liquefied soil behaves as a viscous fluid rather than a ...
Measures to reduce transformer failures in the distribution network of CEB

Wijekoon, VB [Thesis-Abstract]

Ceylon Electricity Board (CEB) has many transformer installations in its distribution network, with their capacities ranging from 100 kVA to 1000 kVA. The latest transformer designs are very much simplified and optimized. ...
Prototype implementation of an islanding detection relay based on pattern classification of current and voltage transients

Lidula, NWA; Rajapakse, AD; Pham, JP; Denboer, N

A prototype islanding detection relay, which uses decision tree classifier to categorize the transient generating events as ‘islanding’ or ‘non-islanding’ was implemented and tested. It consisted of two basic stages of ...
