Building Frames Subjected to 2D Earthquake Motion
Inelastic response of a simplified model of a 10-storey building frame was analyzed to assess the effects of bi-directional seismic loading. Interaction between the strengths in the two...
Seismic Load Effects on a Scaled Model Structure
A long term observation on a scaled steel braced frame model with intentionally reduced seismic strength is ongoing since 1983. This paper examines the seismic load effects of two earthquakes...
Seismic Isolation of Storage Tanks
There has been a significant amount of research activity over the past decade on the seismic design of storage tanks. The seismic design issues and limit states are quite complex due to...
Seismic Large Amplitude Liquid Sloshing?Theory
The sloshing phenomenon in seismically-excited, rectangular, liquid storage tanks is addressed. In particular, a semi-analytical method to study the effects of large amplitude sloshing...
Big-Scaled Tilt Test on Uplifting Behavior of Oil Storage Tanks
The authors conducted a series of static tilt tests using a very big model with the full similitude in order to investigate the uplifting behavior of large-scaled tanks. The model was...
Static Tilt Analyses of Uplifting Cylindrical Tank
This paper describes the general method adopted for predicting the static tilt performance of cylindrical liquid storage tank that is free to uplift. In the analysis described here, the...
Analysis for the Seismic Response of Liquid Containers
An analytical model is presented for the nonlinear response of fluid containers whose bottom may separate from and lift off their foundation, during base excitation. First, the hydrodynamic...
Detection of Seismic Structural Damage
Damage analysis models based on equivalent modal parameters are used to identify the serviceability limit state for structures subjected to earthquake loads. A model for the analysis of...
Seismic Performance of Existing Building in New York City
Strength-based damage indices depending on structural shear capacity and earthquake intensity are used to predict the seismic performance of existing buildings in New York City. Nonlinear...
Seismic Vulnerability and Retrofitting of Buildings. Recent Experiences in Mexico City
Measures taken in Mexico City after the 1985 earthquake to evaluate the safety of existing buildings, to strengthen damaged structures and to retrofit those that were considered to need...
Seismic Vulnerability Evaluation in Japan
The state of the art in Japan is reviewed on the evaluation of the seismic capacity of existing low- to mid-rise reinforced concrete buildings, taking into account the different resistance...
Overview of Published Documents for the Evaluation of Existing Buildings
Presently, the most common procedure used by engineers to evaluate existing buildings is probably a code approach that was developed for the design of new construction. Many engineering...
Seismic Evaluation of Buildings in the Eastern and Central United States
The Applied Technology Council (ATC) has developed and published a methodology, ATC-14, for evaluating specific buildings that is tailored for use by practicing structural engineers. ATC-14...
Seismic Vulnerability and Upgrading of Buildings Geotechnical-Geological Aspects
