The effect of wind force on metal deck roof joint
Wind related damage had been rapidly increase in Malaysia. Previous record most of the failure occurred at roof structure system. Roof metal decking is commonly used now in roof structure system in Malaysia. Pull through failure mostly occurred due to insufficient connection. Therefore this stud...

| Summary: | Wind related damage had been rapidly increase in Malaysia. Previous record most of the
failure occurred at roof structure system. Roof metal decking is commonly used now in
roof structure system in Malaysia. Pull through failure mostly occurred due to insufficient
connection. Therefore this study is conducted to investigate the potential of failure and to
provide the information related to connection in roof metal decking system. From previous
study it was been identify that the maximum failures load of screw connection is 0.99 kN
A general metal roof deck used in Malaysia were identified and been analysed. Two
different connection type were used which is screw and nail in this study. The spacing
between the connection been model are 300 mm, 600 mm, 900 mm and 1200 mm. Finite
Element software were used to analyse the force acting to the connection. From the result it
was shown that the maximum spacing of screw connection to resist wind speed at
32.5
m/s
is 1100 mm. Result also shown that by increasing the spacing distance of connection will
affect the risk to failure. It can be concludes that the spacing of the connection are very
important in order to resist wind storm. |
