Investigation of Shear Lag Factor in Long Structures with Pipeline System in Tubes under Wind Load

The type of lateral load capacity systems is one of the major challenges of structural engineers in implementing and designing high-rise structures. One type of common system is a pipe system in which the type of pipe in the classified pipe exhibits good behavior under wind and earthquake loading conditions. One of the issues that researchers have been studying over the years is the discussion of the shear lag. The lack of a balanced distribution of axial forces in columns is referred to as lateral shear under lateral load. In this study, a 40-story concrete structure with a reinforced barrier system is designed according to ACI 318-11. According to the ASCE7-10 standards, the load factor of the shear lag has been investigated in different of columns in floors. In this paper, ETABS finite element software is exploited to design and analysis the 40-story reinforced concrete building. The floor’s plans are different based on stories range. This model is considered under wind loading condition and the axial force for both middle and corner columns are carried out. The results show thatthe axial load of corner columns are more than the middle columns in the lower floors and for higher floors the middle columns have more load capacity than corner columns.
