<![CDATA[Failure of the roof frame structure can cause to large losses for the owner of the building and threaten the security and safety of building users. Collapse can be caused by planning and implementation factors. In 2016 there was a failure of roof frame structure at Building X in Pekanbaru which resulted in almost the entire roof frame collapsed. Based on visual observation there is failure at connection and buckling in some stems. Through direct observation, Scheme of roof collapse of howe girder type of roof that occurs in part in the supporting span and overall collapse in the main span. The study was conducted by analysis of numerical analysis to determine the instability of truss elements using a computer program in accordance with SNI 7971-2013. The analysis was performed for the collapse pattern of roof truss structure. The analysis includes the aksial force when the structure fails. The result of the evaluation showed that the cold rolled steel roof truss element in building x still did not meet the criteria of SNI 7971-2013 planning. Unstable press element after applied load which has been combined.]]>
