Abstract
In order to make the design of reinforced concrete (RC) special-shaped column frame structure safe and economical, the optimization design of the structure based on the general design is put forward. In the general structural design, there are problems of mismatch in structural arrangement, overall performance parameter and basic component parameter. By optimizing the period ratio, stiffness ratio and displacement ratio of special-shaped column, rectangular column and framed girder, the structure can be improved. Through increasing the strength grade of concrete and the size of the column section, the axial compression ratio of column can be optimized in proportion. The shear pressure ratio of beam-column node area can be improved by increasing the strength grade of concrete, haunching the beam and raising the beam height. According to the engineering practice, the overall performance parameter control reference value of RC special-shaped column frame structure is put forward. The design process of special-shaped column frame structure is introduced with the examples of engineering design and the optimization design result is ideal. Optimization design goal and optimization means of special-shaped column frame structure provide a new design concept for the design of special-shaped column frame structure.
