Abstract

THE STRUCTURE-SOIL-STRUCTURE INTERACTION (SSSI) BETWEEN HIGH-RISE BUILDINGS IS NUMERICALLY INVESTIGATED. ANSYS HAS BEEN FURTHER DEVELOPED FOR CALCULATION IN THE FREQUENCY DOMAIN, IN WHICH HYSTERETIC DAMPING CAN BE CONSIDERED FOR BOTH THE SOIL AND STRUCTURE. THIS STUDY IS PRESENTED IN TWO SUBSEQUENT PAPERS. IN THE FIRST PART, I.E., THIS PAPER, THE VARIATIONS IN THE STORY SHEAR FORCE, INTERSTORY DRIFT ANGLE, DISPLACEMENT, VELOCITY AND ACCELERATION OF THE SUPERSTRUCTURE, THE SWAY OF THE FOUNDATION, AND THE AXIAL AND SHEARING FORCES OF THE PILE ARE PRESENTED. THE MAJOR INFLUENCING FACTORS ARE THE EXCITATION FREQUENCY OF A HARMONIC WAVE OR THE FREQUENCY COMPONENTS OF A SEISMIC WAVE, SHAKING DIRECTION OF AN EXCITING WAVE AND DIRECTION OF THE STRUCTURE ARRANGEMENT. UNDER HARMONIC WAVES, THE INTERACTION MAINLY OCCURS WHEN THE EXCITATION FREQUENCY IS 1-5 HZ. UNDER SEISMIC WAVES, WHEN THE SHAKING DIRECTION OF AN EXCITING WAVE IS PERPENDICULAR TO THE DIRECTION OF THE STRUCTURE ARRANGEMENT AND THE DIRECTION OF THE STRUCTURE ARRANGEMENT IS PARALLEL TO THE LATERAL AXIS OF THE STRUCTURE, THE INFLUENCE ON THE SUPERSTRUCTURE IS GREATEST.
