PRESIDENT’S MESSAGE

I am pleased to send the President’s Message for

the full day seminar on “Advances in Concrete

and Steel Structures” scheduled to be held on 29th

October 2019, at the Oak Room, Cinnamon Grand

Hotel, Colombo. This is the third and the final

seminar for the year 2019, organized by the

Society of Structural Engineers Sri Lanka.

The topics and the resource persons in the seminar

have been selected very carefully to cover a wide

spectrum of local and foreign experiences in both

research and applications in the construction

industry. As such the participants will be

benefited immensely in resolving their issues

related to durability of concrete structures, from

the first presentation which will be conducted by

Prof Anura Nanayakkara.

Our own experience on the designing and

construction of a large water supply project, will

be shared by Eng N A S Shantha, Eng. R S K

Thrimavitharana and Eng. Nageeja Ariyasena.

Although the steel building design and

construction is popular, the behavior of the

buildings under seismic loading and detailing to

mitigate seismic effect is not much applied in the

Sri Lankan context. Prof. Durgesh Rai will touch

this area.

Eng. Inbarajan Rajavel, a very popular resource

person in Singapore and Malaysia, wishes to share

his vast knowledge in the Structural Robustness

and Security in building design.

The BS 5950, the widely design code used in

designing of steel buildings for the last couple of

decades are now outdated and the Eurocodes are

becoming popular in Sri Lanka. The presentation

by Dr (Mrs) Premini Hettiarchchi having her

experience in teaching and research works, will

definitely add more values to the seminar.

The seminar organizing Committee comprising

Eng. Lionel Gunawickrama (Chairman), Eng.

Aravinda Kalugaldeniya and Eng. Y Goguladas

have made our effort of having a more useful

event, a success. The Executive Committee

Members and the Associate Member Chapter

Committee are also behind the success. Dr. Nihal

Somarathne and Eng. K L S Sahabandu, past

President of SSESL shall chair the morning and

afternoon sessions to ensure the time is best

managed and the audience is given the

opportunity to discuss issues effectively.

The Platinum sponsors Insee Cement and Melwa

Rolling (Pvt) Ltd have relieved the Society from

the financial burdens and made participants more

comfortable in the registration. I humbly request

all the participants to make use of this opportunity

to strengthen the knowledge, henceforth making

our vision completed.
