Scope and Objectives

Code of Practice for Structural Use of Glass 2018 was launched on 9 February 2018 by Buildings Department. For the new safety requirements against broken glass, laminated glass would be required for balustrade and large-scale glass wall systems. In current local practice, the laminated glass is conventionally designed by using the individual glass pane stiffness without composite action. Simplified design provision for laminated glass with composite action is introduced in the new Glass Code together with some quality control testings.


Principal feature of laminated glass is the safety performance under impact and breakage. The interlayers absorb the energy of the impact and resist penetration. Although the glass may break, the glass fragments remain firmly bonded to the interlayer, minimizing the risk of injuries. There is always the possibility of glass breakage in glass skylights, canopies, sloped glazing, glass floor, glass staircase etc. and glass balustrade. Without laminated glass, that could mean a big safety problem caused by shattering glass.


Moreover, there is an increasing trend in the use of laminated glass in residential buildings, commercial buildings and retails. This trend is being driven by the increased desire for more open designs with less visible framing and structural supports, resulting in glazing designs that provide greater transparency and visibility. Glass laminates such as SentryGlas® ionoplast are able to fulfill the high architectural safety standards at a reduced thickness compared to glass laminates with PVB interlayer. SentryGlas® interlayer was chosen primarily for its enhanced strength compared to laminates with PVB (which allowed a 30% thinner glass construction), its post-glass breakage retention properties and its visual clarity when used in combination with low-iron vision glass.

Mr Malvinder Singh Rooprai
Malvinder Singh Rooprai is working for Trosifol® PVB division of Kuraray India Pvt. Ltd as Technical Consultant for Asia Pacific region. Kuraray acquired the Glass Laminating Solutions Business of DuPont in June 2014 and is based out of New Delhi. He works on finite element modeling of laminated glass for analyzing the effects of viscoelastic behavior of polymeric interlayers on the structural performance of laminated glass panels in architectural applications. He has provided consulting reports on structural performance of laminated glass to Architects and Façade Engineers and Structural consultants on some of the mega projects in the region like Shanghai Tower in China and World One in Mumbai – India. He has presented papers on laminated glass with SentryGlas® in events like GPD Finland, World of Facades (India) & Façade Design and Engineering Conference and presented on the same in similar events in Singapore.


He has worked as a Structural & Façade Engineer for nearly 6 years with a façade fabrication company (a subsidiary of construction giant DLF Ltd) in India. He did his Masters in Structural Engineering from Thapar University, Patiala – India and did his dissertation work on Wind Load Modeling in Tall Rectangular Buildings including Interference effects by Artificial Neural Networks.


His lecture will focus on Structural Analysis and Behaviour of Laminated Glass
• Various Analysis Methods
– Empirical Formulas
– Effective Thickness Method (Advantages & Limitations)
– Finite Element Method
• Bond Strength Measurements for interlayer at Elevated Temperatures.
