Seismic Evaluation of a Tall Reinforced Concrete Frame Building
Accelerations at basement, fifth and tenth floor levels of a reinforced concrete apartment building were recorded during the October 1st, 1987 Whittier-Narrows earthquake. These accelerations...

Hydrodynamic Interaction Effects in Earthquake Response of Arch Dams
With the aid of earthquake response results it is demonstrated that the following hydrodynamic effects should be considered in the analysis of the earthquake response of concrete arch...

Hydrodynamic Isolation of Concrete Dams
The feasibility of reducing hydrodynamic effects in the earthquake response of concrete dams by anchoring gas-filled balloons or injecting bubbles in the water is investigated. Significant...

Seismic Evaluation of PG&E Concrete Dams
Seismic evaluation of PG&E concrete dams is an ongoing process. The seismic environment for the dams changes over time because more historical earthquake data is obtained, faults...

Ductility and Failure Characteristics of Concrete and Rock Subjected to Complex Load Paths
Strength, ductility and the complex material response features of concrete and rock should be evaluated through carefully planned material properties test programs designed to subject...

Earthquake Induced Cracking in Concrete Gravity Dams
An important nonlinear behavior in the earthquake response of concrete gravity dams is the formation and propagation of tensile cracks in the concrete. The earthquake response of a typical...

Seismic Design of Highrise Building with Mega Frame
The NEC corporation head office building is under construction at Shiba Minato-ku, Tokyo, Japan. This building is a highrise building of steel structure with the height of 180m. The structural...

Structural Considerations in Design and Construction Process of a 25 Story Office Building
This paper introduces an example in which a steel office building of 25 stories above the ground was constructed employing innovative techniques. One of them was the use of precast concrete...

Seismic Design of a Long-span Space Structure
This structure consists of a 5 layered complex shape of long-span steel roof structure, and reinforced concrete (RC) and steel reinforced concrete (SRC) supporting structures. The roof...

Implications for Limit State Design of Inverted V Braced Steel Structures
Inverted V braced steel structures with backup ductile moment-resisting frames forming a dual system, exhibit complex inelastic behavior under severe seismic excitations. Thus, current...

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 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...

Buckling Criteria for Earthquake-Induced Overturning Stresses in Cylindrical Liquid Storage Tanks
Perhaps one of the most common forms of seismic damage to cylindrical liquid storage tanks made out of steel is buckling of the tank wall due to vertical overturning stresses. Buckling...

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...

Biaxial Damage Assessment
The structural system under investigation is a frame subject to seismic excitations. The analysis accounts for the spatial distribution of beams, columns and bracing system. It also considers...

Normalized Damage Index for Evaluation of Buildings
A conceptual model for evaluation of structural damage is developed based on the fundamental idea of demand and capacity. The proposed formulation combines two recognized sources of damage:...
