[Virtual Presenter] Hi, good morning, everyone! Thank you to everyone for being here with us today. We are very pleased to welcome you to join today webinar with the topic of “Design Optimisation of Metal Roof Flashing & Capping - For Sustainable Watertightness and Perfect Aesthetics”. Brought to you by NS BlueScope Lysaght. We appreciate very much if you can mute your mic during the session and you can raise your question from time to time by type into the chat box with your email address. I will try my best to answer your questions in the end of this webinar. Otherwise, I will return an email to you to answer your questions.. 

Scene 1

Optimising Structural Integrity: Load Considerations in the Design of Metal Roofs, Walls, and Steel Decking

[Audio] Alright! That's it for my sharing session today. Feel free to ask any questions or you would like to clarify anything that is not clear. Thank you! Let us take a look on the chat box and see any questions are posted.. 

Scene 2

[Audio] This session will be focusing on different type of standard flashings that are commonly use on roof and wall. In addition, I will present some customised flashing and rainwater goods as well. Then, some case study will be shared. At the end of this session, we will open Q&A session to all the audiences.. 

Scene 3

Wind Load Calculation According to MS EN1991-1-4

How to Determine the Wind Uplift Capacity of Metal R&W Product?

How to Choose the Right Metal R&W Product Based on Calculated Wind Load?

[Audio] Without further ado, let's start with the first topic of today – Definition of Flashing. 

Scene 4

Choose the right product to resist wind load. How can I assure these products can resist the calculated wind load?. 

Scene 5

Choose the right product to resist wind load

How can I assure these products can resist the calculated wind load?

Point 1: MS2523. Static Wind uplift test requirement according to MS2500. 

Scene 6

Static Wind uplift test requirement according to MS2500

The mechanical performance of the product shall be stated by the manufacturer together with
details of how the values were determined in accordance with the national regulations of the
country in which the product is to be used. For calculation and testing either national regulations
or MS EN 1993-1-3 may be used.
Calculation and test methods referred to in this standard mainly deal with trapezoidal and
sinusoidal sheets.
Tiles, standing seam sheets and concealed fix sheets are used in proprietary roofing systems;
no structural requirements are given within this standard for these products. These products
should normally be designed by testing, i.e. load test are not applicable.

MS2500, Clause 4.3.2 Calculation and Test of Mechanical Resistance

Point 3: Trust on the testing done by manufacturers

Testing?. Calculation?. Wind uplift capacity performance of metal roof and wall.

Which is the easiest way to get the accurate answer?. 

Scene 12

Which is the easiest way to get the accurate answer?

The way to test the pressure capacity of metal roof and wall. 

Scene 13

The way to test the pressure capacity of metal roof and wall

The value of the pressure capacity of a cladding is determined by full-scale testing on a pressure rig
 The testing is conducted to the requirements of : AS1562.1 AS4040.2

[image] Testing was conducted in accordance with AS 1562.1:1992 Design
and Installation of Sheet Roof and Wall Cladding—Metal, and
AS 4040.2:1992 Resistance to Wind Pressure for Non-cyclonic
Regbns.
The pressure capacities for serviceability are based on a deflection
limit of (span/ 120) + (maximum fastener pitch/30).
The pressure capacities for strength hue been determined by
testing the cladding to Éilure (ultimate capacity). These pressures
are applicable when the dadding is fixed to a minimum ofl .Omm,
G550 steel. For material less than 1 Omm thick, seek advice from
our information line.

undefined. The way to test the pressure capacity of metal roof and wall. 

Scene 14

This video show the time lapse of wind uplift testing example.
 The product was tested in serviceability and strength.
 We harvest data in TWO PARTs: The serviceability pressure at the limited deflection.
 The strength pressure at the failing point of product.

Determine the final pressure capacity. We will apply factors into the raw data according to According to AS 1562.1:2018, PART 5, Clause 5.3, Table 5.1. We can do interpolation to get the intermediate wind uplift capacity. For example, we tested 900mm and 1500mm span. Then, we get the value of 1000mm and 1200mm by interpolation. However, you are not allowed to extrapolate the value to get the figure out of the range. This final data will be published in brochure as wind uplift capacity table of a product..

Alright! That's it for my sharing session today. Feel free to ask any questions or you would like to clarify anything that is not clear. Thank you!

Let us take a look on the chat box and see any questions are posted.

This session will be focusing on different type of standard flashings that are commonly use on roof and wall. In addition
 I will present some customised flashing and rainwater goods as well. Then
 some case study will be shared.

At the end of this session
 we will open Q&A session to all the audiences.

Without further ado
 let's start with the first topic of today – Definition of Flashing
