Theoretical Results

The interstory drift of frame structures is caused by beams, columns and joints. The calculation formula of storey yield drift for reinforced concrete frame structures is obtained by adding above three kind of deformation, and the comparative analysis show that theoretical results have good consistency with experimental data. The expression formula of storey yield drift angle for steel reinforced concrete (SRC) frame structures are analyzed by using the same hypothesis and methods, and quantified performance index for SRC frames having a certain guarantee value are proposed according to relationship of four seismic performance levels. The conclusion obtained provide basic information for performance-based seismic design of SRC frame structures.

Dynamic Nonlinear Analysis

The randomness and uncertainty of seismic demand and structural capacity are considered in demand-capacity factor method (DCFM) which could give confidence level of different performance objectives. Evaluation steps of investigating seismic performance of steel reinforced concrete structures with DCFM are put forward, and factors in calculation formula are modified based on stress characteristics of SRC structures. A regular steel reinforced concrete frame structure is analyzed and the reliability level satisfying four seismic fortification targets are calculated. The evaluation results of static and dynamic nonlinear analysis are compared which indicates that the SRC frame has better seismic performance and incremental dynamic analysis could reflect more dynamic characteristics of structures than pushover method.
