This research is for investigating the pre-engineered steel buildings according to deformation systems considering semi-rigid connection, which is considered as a correct model. Semi-rigid connection was proposed by Aleksander. K, in which the value of semi-rigid joint is dependent on connection types, material and section details. | N. T. Ha L. T. Hai C. T.

INVESTIGATION OF PRE-ENGINEERED STEEL BUILDINGS ACCORDING TO DEFORMATION SYSTEMS CONSIDERING SEMI-RIGID CONNECTION Nguyen Trong Ha Le Thanh Hai Cao Thi Hao Faculty of Civil Engineering Vinh University Received on 26 8 2018 accepted for publication on 05 11 2018 Abstract This research is for investigating the pre-engineered steel buildings according to deformation systems considering semi-rigid connection which is considered as a correct model. Semi-rigid connection was proposed by Aleksander. K in which the value of semi-rigid joint is dependent on connection types material and section details. In this research the deformation systems were analyzed using second order effects P-A effects by Sap2000. P-A effects and semi-rigid connection were simultaneously combined in evaluating the internal forces and displacement of the structure. In order to evaluate the accuracy of the current research method the results were then compared with those designed by the current Vietnamese standard. The results show that the combination of P-A effect and semi rigid connection have great effect in calculate the pre-engineered steel structures compared with other models. 1. Introduction In present the Vietnamese standard of Steel structures are used in designing the pre-engineered steel buildings in which the joints between beam and column is considered rigid. However these connections are not totally rigid. Therefore the design structures of pre-engineered steel buildings using the current Vietnamese standard is approximate and there are potential risks. The considering of semi-rigid connections of steel structures has been researched by various researchers in the world. In 1934 Batho and Rowan proposed the straight-line common beam method to classify semi-rigid connection 2 . In 1936 Rathburn considered the stiffness of the connection in the moment distribution method 8 . Baker William and .
