The effect of vertical near-field ground motions on the collapse risk of high-rise reinforced concrete frame-core wall structures

Arsam Taslimi et al.

Summary: This study investigated the variation in collapse risk of RC buildings under bi-directional ground motions, finding that structures were more likely to meet collapse criteria in the H+V state, leading to increased collapse risk. Considering the impact of vertical ground motions on buildings can result in a more accurate evaluation of their seismic performance.

Analytical approach for vertical floor acceleration of regular RC frames under earthquake excitation

Yang Xiang et al.

Summary: This paper proposes an analytical method for estimating VFA in regular RC frames, showing that the VFA could be significantly larger than the peak vertical ground acceleration. The research reveals important features of VFA and highlights the nonlinear relationship between VFA and building height due to the effects of higher-order modes.

The influence of the vertical component of ground motion on the probabilistic treatment of the rocking response of free-standing blocks

Christos G. Lachanas et al.

Summary: This study investigates the influence of the vertical component of ground motion on the distribution of seismic response of unanchored rigid blocks. The results show that the vertical component can have a significant but highly variable effect on the rocking response on a single record basis, sometimes detrimental and sometimes beneficial. However, when considering a large ensemble of records, the influence becomes statistically insignificant, except for the specific case of rocking uplift for stocky blocks. Closed-form expressions are proposed to modify the fragility function for rocking initiation in cases where uplift is associated with damage.

Evaluation of the Floor Acceleration Response Spectra of Numerical Building Models Based on Recorded Building Response Data

Hamidreza Anajafi et al.

Summary: Recorded floor acceleration data from instrumented buildings are used to evaluate the impact of different parameters on the seismic response of nonstructural components. Relationships proposed by the authors for estimating NSC damping modification factor are validated using this data.

Seismic response of acceleration-sensitive nonstructural components in a Thin Lightly-Reinforced Concrete Wall (TLRCW) mid-rise building

Juan Carlos Obando et al.

Summary: Recent experience in earthquakes has highlighted the significance of Non-Structural Components (NSCs) in multi-story buildings on economic losses. This study examines the floor accelerations in a novel structural system, the Thin and Lightly-Reinforced Concrete Wall (TLRCW) building. The seismic demands on NSCs in a TLRCW building are calculated and compared with current characterizations. The research finds that floor accelerations can be very large under design-level seismic demands, and the current characterizations provide reasonable approximations.

Experimental Seismic Assessment of Nonstructural Elements: Testing Protocols and Novel Perspectives

Martino Zito et al.

Summary: Nonstructural elements (NEs) are elements within buildings/facilities that are not part of the structural system, classified as architectural elements, mechanical/electrical/hydraulic systems, and building contents. They pose a critical seismic risk due to their vulnerability and exposure, especially for critical facilities like hospitals and nuclear plants. The study reviews international testing approaches and protocols for seismic assessment of NEs, providing technical guidance for implementation and proposing a unified approach for their qualification.

Impact of the Vertical Component of Earthquake Ground Motion in the Performance Level of Steel Buildings

Jesus-Gerardo Valdes-Vazquez et al.

Summary: This study focuses on the impact of considering the vertical component of earthquake ground motion on the non-linear dynamic response of buildings, finding that larger plastic rotations in beams are obtained when both horizontal and vertical components are considered simultaneously. It is suggested that including the vertical component in the analysis may lead to beams having performance within a different acceptance criterion.
