107 Collapse Performance Evaluation of Reinforced Concrete Special Moment Frame Systems Considering Soil Structure Interaction Saeed Hagholahiy saeed hagholahiy@gmail com Date of Submission 2013 01 24 Department of Civil Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language FarsiSupervisors Dr Farhad Behnamfar farhad@cc iut ac ir AbstractSoil Structure Interaction SSI as a complex phenomenon resulting in positive or negative effects onseismic behavior of structures has long been a focus for research The general belief of its decreasing effecton structural forces has resulted in it being usually neglected in the design of ordinary buildings This iswhile the soil structure interaction effects change the dynamic responses and this alteration can have adecisive effect Today with the spread of the performance based design concepts accounting for soil structure interaction has become increasingly more important Soil Structure Interaction SSI can alter theperformance of structure totally including its dynamic characteristics response maxima and moreimportant distribution of nonlinear response through structure the accurate calculation of which is vital forperformance evaluation Collapse prediction of special RC moment frames has been subject of manyresearch works in the past For instance FEMA P695 proposes a methodology for implementing the sametask although without regard for soil structure interaction This study describes an application of FEMAP695 methodology for assessing collapse performance of reinforced concrete RC structures including theeffect of soil structure interaction The collapse capacity of structure is determined using an incrementaldynamic analysis with a suite of appropriate earthquake records and the fragility curves are derived forstructural collapse In the current study the method of beam on nonlinear Winkler foundation is utilized The soil model consists of spread nonlinear vertical springs along the foundation being able to include therocking subsidence and uplift degrees of freedom and the radiation damping In addition Winklerfoundation is made of horizontal springs to model lateral slip of the foundation as well as the passive soilpressure Also in this study the collapse of structure envelopes dynamic instabilities including lateraldeformations P effects and strength degradation of structural elements In this research special RCmoment frames in 4 8 12 and 16 stories are designed for B C and D type soils of ASCE 7 10 and then theirfragility curves are produced using an incremental dynamic analysis procedure Effect of a flexible base isincluded in the model with the help of a Winkler foundation Results point out the increasing probability offailure for a structure on softening bases for the same spectral acceleration Keywords Collapse soil structure interaction RC special frame Winkler spring incremental dynamicanalysis
