Embankment performance under earthquake loading
… of a functioning network is heightened in a post-earthquake situation. More stress is placed on road networks to provide transportation for rescue, repair, and relief teams. Roads, approaches, and embankments represent significant elements in the transportation network. Understanding the …

Performance of Full-Scale Reinforced Concrete Columns Subjected to Extreme Earthquake Loading
… the program was to investigate the influence of loading history, thus the column specimens were subjected to several large displacement loading protocols, including monotonic and uniaxial and biaxial cyclic loading protocols. The last overall goal of the program was to investigate the post-peak …

Theoretical investigation of Australian designed reinforced concrete frames subjected to earthquake loading
Studies the behaviour of reinforced concrete frame structures designed in accordance with AS3600 concrete structures code using a non-linear computer model. A computer model of a multi-storey multi-bay prototype structure was created.

Performance of Reinforced Concrete Edge Beam -Column -Slab Connections Subjected to Earthquake Loading
"In seismic analysis of MRFs, beam-column connections are often modeled with rigid joint zones. However, it has been demonstrated that, in ductile RCMRFs designed based on current codes (to say nothing of older non-ductile frames), the joint zones are in fact not rigid, but rather undergo …

The influence of cementation on liquefaction resistance of sands
… when they are saturated and subjected to earthquake shaking. Considerable study has been directed towards this subject over the past 20 years in recognition of the possibility of large-scale property damage or loss of life due to this type of failure. Recent evidence has shown that small …

Stochastic Seismic Performance Evaluation of Buildings
… various levels of damage or become unsafe due to earthquake loading during its lifetime. Uncertainties in the dynamic analysis associated with both the loading and the prediction of the structural response are considered.

Seismic response of transformer bushing systems and their rehabilitation using frictional pendulum system
… power transformers and their attachments under earthquake loading. It begins with the description of the transformers, attached bushings, and some typical examples of substation failures in earthquake loading. This is followed by the development of finite element model of three different sizes …

Seismic analysis of a large size underground cavern
… are generally assumed to be much safer to earthquake loading, compared to above surface structures. However, many large underground structures have witnessed great damage in recent earthquakes. Thus underground structures in earthquake prone zones should be designed to withstand both static …

An Analytical Study of the Interaction of Frames and Infill Masonry Walls
… of frames, although properly designed to resist earthquake loading when acting alone, being severely damaged due to the presence of infill masonry walls acting in the plane of the frame. In this study a nonlinear dynamic model to study the behavior of frames infilled by masonry walls has been …

Damping and flexural properties of prestressed concrete members subjected to reversed cyclic loading
… the problem of using prestressed concrete for earthquake resistant structures, and examines the "equivalent viscous damping" approach to the measurement of structural damping. Part two describes the reversed cyclic testing of prestressed concrete members: end moments were applied to the members …

Quick methods of analysing earthquake forces on viaduct bridges having continuous decks and tall piers
… available methods of calculating the effects of earthquakes on viaduct-type bridges with continuous decks and tall piers are examined. Particular emphasis is laid on the use of a relatively quick method of analysis using response spectra and taking account of the effects of damping. The use of …

Study of base isolation systems
… fixed base and base isolated schemes to severe earthquake excitations. Techniques for modeling the superstructure and the isolation system are also described. Elastic time-history analyses were carried out using comprehensive finite element structural analysis software package SAP200. Time …

The impact of high frequency/low energy seismic waves on unreinforced masonry
Traditionally, the high frequency components of earthquake loading are disregarded as a source of structural damage because of their small energy content and because their frequency is too high to resonate with the natural frequencies of structures. This thesis argues that higher frequency waves …

Time history analysis of axial forces (Pass Through Forces) at joints in a braced frame
… will be used to find precise values under earthquake loading. The results are compared with two traditional methods of finding pass through forces, and the best approach is identified.

Design optimization of cable-stayed bridges
… the analyses of ten different 3D models under earthquake loading. The numerical results of the analyses form the basis for the optimization of the bridges' designs. This study has indicated that for the specific design examined, the optimum cable spacing is: 13.2m and 12.39m for equivalent …

Seismic retrofitting of deficient Canadian buildings
… As a result, these structures are vulnerable to earthquake loadings and are in urgent need of repair and retrofit. This thesis provides a literature review of the vulnerability of Canadian infrastructures built prior to the development of seismic design provisions in actual codes of practice and …

Seismic Behavior of Simcon-Jacketed High Strength Lightweight Aggregate Fiber Reinforced Concrete Filled Steel Tube Column Members
Earthquake resistant structures and structures deteriorated due to earthquake and lack of durability inspired engineers to develop novel structural systems. During the recent decades advanced fiber reinforced cementitious composites such as High-Performance Fiber Reinforced Concretes (HPFRCs) have …
