Seismic behavior of RC structures with absence of floor slab constraints and large mass turbine as a non-conventional TMD: a case study

Abstract: This paper presents a case study on the influence of absence of floor slab constraints and large mass turbine as a non-conventional tuned mass damper (TMD) on the seismic behavior of the structure and members. The investigated structural system is a reinforced concrete (RC) shear wall-frame power plant structure with large slab openings and a large mass turbine. In RC structures, the existence of floor slabs can usually provide strong constraints on beams so as to greatly increase their bearing capacity. Howev… Show more

“…Numerical simulations and shaking table tests are conducted to study the isolation mechanism and seismic performance of the proposed separated 3D isolation scheme. In addition, as the isolation of the floor slabs weakens the constraint of the floor slabs to the beam and column members as in a traditional frame structure, 29 the influences of releasing floor slabs to the dynamic properties as well as the seismic behaviors of the structural members are investigated.…”

“…Following his work, the effectiveness of frictional, viscoelastic, and tuned mass dampers in asymmetric systems was explored . Meanwhile, other researchers have emphasized on PED systems for vertically irregular structures, such as the multistory building structure with weak stories or uneven mass distribution caused by staggered floors, slabs with large openings, or heavy machineries. However, for more complex structures with both horizontal and vertical irregularities, such as the single‐column elevated station focused on herein, studies regarding effective PED systems and the assessment of their influences on structural seismic performance are rare.…”

“…e noncritical components in the structure, such as filled walls and floors, can also be used as the mass blocks to form a large mass ratio TMD [18,19]. In addition, the heavy equipment in an industrial plant can be constructed into a large mass ratio TMD in the form of suspension or isolation [20]. For example, in the typical coal-fired power plant, nonstructural coal buckets are used as the mass blocks of TMD or MTMD, which are called the coal bucket dampers.…”
