- Research and practice of response control for tall buildings in mainland China
- X. Lu ; H. Jiang
- Book Title / Journal: Procedia Engineering
- Year: 2011 , Volume: Vol.14 , Series:
- Earthquake engineering
- Description
- In the recent two decades a large amount of tall buildings have been constructed in Mainland China, offering goodv opportunities of research and practice for Chinese researchers and practioners in the field of structural engineering. Some research and practice achievements of response control for tall buildings in Mainland China in recent five years are introduced here, focusing on the performance-based seismic analysis and design of code-exceeding tall building aiming to design structures with predictable seismic performance in the future earthquake, shaking table model tests on complex tall buildings to evaluate the seismic performance of structures and accordingly revise the structural design, and the application of structural control technologies to better protect tall buildings from winds and earthquakes. Some typical examples of practical application, such as application of active tuned mass dampers (ATMD) in Shanghai World Financial Center Tower and application of deformation-related with damping and stiffness dampers in Zhengda Himalaya Hotel, are presented.

- Failure mode of columns of existing R/C building damaged during the 2007 Niigata Chuetsu-Oki Earthquake

- Description
- The school building investigated was a 3-story reinforced concrete (R/C) building built in 1963. The building suffered from a great deal of damage during both the 2004 Chuetsu Earthquake and the 2007 Chuetsu-Oki Earthquake. The damage of the first and second floors during Chuetsu Earthquake was light and that by Chuetsu-Oki Earthquake was moderate. The previous study revealed that the anticipated design failure modes of most of the columns of the building were flexure although most of them actually failed in shear during the 2007 earthquake. This is an important problem to be studied. In order to study the reason why the columns failed in shear rather than in flexural, a parametric study was conducted, paying attention to parameters including the strength of concrete, hoop spacing and subjected axial force. But those studies could not explain the real phenomenon clearly. After that the effects of cutoff location of longitudinal reinforcement bars were examined and it was concluded that the diagonal crack generated from cutoff point caused shear failure in these columns.

- Cyclic test of a coupled steel plate shear wall substructure

- Year: 2011 , Volume: Vol. 14 , Series:
- Earthquake engineering
- Description
- This research aimed to investigate the seismic behavior and design of the Coupled Steel Plate Shear Wall (C-SPSW). A prototype six-story C-SPSW building was designed based on the model building code. A 40% scale specimen was constructed as the bottom two-and-half-story substructure of the six-story C-SPSW prototype. The reduced scale substructural specimen was cyclically tested using the Multi-Axial Testing System (MATS) at the National Center for Research on Earthquake Engineering (NCREE). In addition to the cyclic lateral forces, the constant vertical loading and cyclic overturning moments were applied on the specimen simultaneously. The test results show that the CSPSW specimen behaved in a ductile manner and dissipated significant amounts of hysteresis energy during the cyclic loadings. Finally, based on the experimental results, the implications in the capacity design for the bottom boundary column are discussed. A numerical simulation using finite element model was conducted. The analytical results quite match the overall and local experimental responses.

- Seismic analysis of a typical masonry building from Barcelona’s Eixample District
- C. Potter
- Book Title / Journal: M.Sc Thesis, Universitat Politècnica de Catalunya
- Year: 2011 , Volume: , Series:
- Earthquake engineering
- Description
- The historic Eixample district of Barcelona is characterised by its beautiful avenues, laid out in grid
across the city. At first impression, the buildings lining these avenues appear identical, an unending
façade built to house the new Barcelona of the 20th Century. The unreinforced masonry buildings that
typify the development remain in use today, largely unaltered since their construction.
Unreinforced masonry buildings are among the most vulnerable structures to damage from seismic
actions. For the masonry buildings of the Eixample that house over 15% of the population of
Barcelona, this is no exception. This study performs a seismic analysis on a typical masonry building
of the Eixample to estimate and assess this damage. By doing so, it aims to estimate the likely
damage due to seismic actions, to identify critical elements of the structures and to quantify the need
for seismic risk maintenance and response plans.
The analysis uses the N2 Capacity Spectrum Method (Fajfar, 2000), adopted by Eurocode 8, to
determine the displacement demand of possible earthquake scenarios. A seismic hazard analysis
determines the seismic demand using deterministic, probabilistic and current European and Spanish
code provisions. The seismic demand is then compared to the results of a non-linear pushover
analysis completed using software DIANA (Version 9.4). The model geometry was based upon plans
of a building that well represents the typical unreinforced masonry buildings of the Eixample.
