Abstract
In order to meet the requirements of architectural design form, a high-rise library project appeared many structural seismic designs, such as plane thin waist concave, large area floor missing, tower offset and torsion irregularity. In accordance with the principle of economy, safety and reliability, many calculation measures are adopted in the structural design, such as the comparative analysis of software SATWE and ETABS, the special calculation of floor stress level, the combining floor analysis of missing floors and the strengthening performance analysis under medium and large earthquake. At the same time, according to the structural transfinite items, the structural strengthening measures are taken, such as optimizing the structural layout, reducing the eccentricity, increasing the thickness of the floor at the weak position, and adding diagonal reinforcement in the stress concentration area. Using the above treatment, the structure can meet the fortification target under three levels.
