Synopsis:

Curvilinear architectural forms may be classified into developable forms, synclastic forms, anticlastic forms, and free-form. The surfaces of developable, synclastic, and anticlastic forms are mathematically derived from equations of straight lines and curved lines. The surface of free-form shapes, however, is derived from NURBS (Non-uniform rational B-Spline) technique. The presentation traces broadly and briefly the various types of curvilinear architectural forms and the associated structural systems. 

The structures of contemporary curvilinear forms are mainly executed in steel. The structures consist of a framework of crisscrossing steel members that are connected at specially jointed nodes and are mutually reinforcing. Curvilinear steel structures thus use relatively small sized members to achieve very large spans. They have a very low weight to span ratio and are capable of catering for complex architectural design forms. 

The presentation showcases the canopy structure of the plaza at the boating ticket office at Taman Botani Kuala Lumpur, designed by award-winning firm GDP Architects Sdn Bhd. It comprises a free-form reticulated surface that is structured from RHS arranged in a triangular configuration. Due to the free-form nature of the canopy each jointing node for the RHS members is different. It is the unique design of these nodes that make the construction of the canopy possible. PERI Malaysia, the proprietor of the detailing design and construction method, shall be invited to share and demonstrate their experience in this freeform shell structure, which is the first of its kind in Malaysia.




    Topic: Structural Deformation Monitoring System Using Geospatial Technique

Speaker: Assoc Prof Dr. Abd Nasir Matori [UTP]

Date :  12 April 2017

Time:   12.10 pm - 1.10 pm  
  

Venue : Seminar Room 2

Speaker profile:

Assoc. Professor Dr Abd Nasir Matori obtained his PhD from University of Newcastle upon Tyne UK in 1996. Over almost 20 years in academia Dr Nasir has specialized in geodesy and geospatial analysis for several engineering applications such as offshore platform subsidence and structural monitoring. Dr Nasir is currently a faculty member of Civil and Environmental Engineering Department of Universiti Teknologi PETRONAS (UTP) as well as the member of the Offshore Engineering Centre of UTP (OECU). Amongst his involvement in structural deformation monitoring using geospatial techniques are offshore platform deformation monitoring using Global Navigation Satellite System (GNSS/GPS), Offshore platform and onshore gas terminal complex deformation monitoring using PsInSAR technique and man-made slope monitoring using Unmanned Aerial Vehicle (UAV) and Close Range Photogrammetry (CRP) technique. As part of his expertise visibility in this area, he has been awarded research grant amounting almost RM 1 million from various research funding agencies. At least 30 of his latest finding in his research was published in indexed publications. 

Synopsis:

Due to aging and prolonged exposure to external loads, engineering structures may experience deformation (i.e. alteration of shape and/or dimension), which may affect the performance of their intended function, it is very crucial structural deformation monitoring and analysis to be conducted, as part ‘Structural Health Monitoring (SHM)’ of these structures for the purpose of optimizing performance, enhancement of operational safety and predictive maintenance. Deformation monitoring system architecture will involve an array of sensors (geospatial, geotechnique etc…) to log ‘periodically sampled deformation-causing data’, measurement interval and deformation analysis. This talk will highlight deformation monitoring system using geospatial technique, its advantages and will showcase some examples of the previous deformation monitoring and analysis done using this technique.
