" Inclined Columns Project " Design of Multi-Story Reinforced Building with Inclined Columns A comprehensive project in the study of Inclined Columns gives an integrated study to know the behavior of this type of columns in the Republic of Yemen in analysis and design and its effects on the structural system used. Inclined columns, which extend approximately 25 meters high through seven floors, were used in the four corners of a commercial facility. An earthquake-resistant investment, the study aims to solve the traffic problem at the point of entry of cars to the car parks at the bottom of the facility, which has turned from a traffic merging point for three traffic directions to a collision point. Yemeni architecture, and a proven study of these pillars in a society that believes that the tendencies of parts of the facilities reflect their imbalance and instability. The study dealt with the operational aspects in which the implementation process is difficult, and what economic changes may occur as a result of the effects of connecting tilted columns in the vertical and horizontal elements of origin, and ensuring a safe and stable link between them. The study also dealt with the proposed structural systems for this type of facilities, and what changes were added by the opposite tendencies between the upper and lower tendencies, and the extent of their impact on the economic design in the sections of the elements. The study gave an illustrative vision about the use of dynamic analysis methods in the vertically and horizontally irregular structures, the steps of conducting the analysis and studying the phases and distortions that may occur in the facilities, in addition to the differences in the methods of distribution of forces from the usual, and the design codes from the procedures of the dynamic methods and directly followed by static methods.
