TOSCA: a Tool for Optimisation in Structural and Civil engineering Analyses
International Journal of Advanced Structural Engineering - Tập 10 - Trang 401-419 - 2018
Many structural engineering problems, e.g. parameter identification, optimal
design and topology optimisation, involve the use of optimisation algorithms.
Genetic algorithms (GA), in particular, have proved to be an effective framework
for black-box problems and general enough to be applied to the most disparate
problems of engineering practice. In this paper, the code TOSCA, which employs
genetic...
Distortional buckling behaviour of intermediate cold-formed steel lipped channel section with various web stiffeners under compression
International Journal of Advanced Structural Engineering - Tập 10 - Trang 189-198 - 2018
The aim of the study is to investigate the distortional buckling behaviour of
intermediate cold-formed lipped channel section under pinned end condition
subjected to axial compression. An extensive test and numerical investigation of
cold-formed lipped channel column with various types of intermediate web
stiffeners is presented. In this study, three types of intermediate web
stiffeners are chosen...
An experimental investigation on the ultimate strength of epoxy repaired braced partial infilled RC frames
International Journal of Advanced Structural Engineering - Tập 6 - Trang 1-7 - 2014
Due to earthquake, buildings are damaged partially or completely. Particularly
structures with soft storey are mostly affected. In general, such damaged
structures are repaired and reused. In this regard, an experimental
investigation was planned and conducted on models of single-bay, single-storey
of partial concrete infilled reinforced concrete (RC) frames up to collapse with
corner, central and...
Finite element analysis of steel fiber-reinforced concrete (SFRC): validation of experimental tensile capacity of dog-bone specimens
International Journal of Advanced Structural Engineering - Tập 6 - Trang 1-8 - 2014
Finite element analyses are conducted to model the tensile capacity of steel
fiber-reinforced concrete (SFRC). For this purpose dog-bone specimens are casted
and tested under direct and uniaxial tension. Two types of aggregates (brick and
stone) are used to cast the SFRC and plain concrete. The fiber volume ratio is
maintained 1.5 %. Total 8 numbers of dog-bone specimens are made and tested in a
1...
An improved CWT-based algorithm for the generation of spectrum-compatible records
International Journal of Advanced Structural Engineering - Tập 5 - Trang 1-7 - 2013
The seismic design of most civil structures is usually accomplished using the
response spectrum approach or simplified equivalent lateral force methods.
However, some special tasks require the use of dynamic time history analyses. In
the nuclear industry, for example, dynamic analyses are required in the design
verification and seismic assessment of critical buildings and in the development
of flo...
Erratum to: Boundary element analysis of post-tensioned slabs
International Journal of Advanced Structural Engineering - Tập 9 Số 1 - Trang 95-95 - 2017
Behavior of wet precast beam column connections under progressive collapse scenario: an experimental study
International Journal of Advanced Structural Engineering - Tập 6 - Trang 149-159 - 2014
Progressive collapse denotes a failure of a major portion of a structure that
has been initiated by failure of a relatively small part of the structure such
as failure of any vertical load carrying element (typically columns). Failure of
large part of any structure will results into substantial loss of human lives
and natural resources. Therefore, it is important to prevent progressive
collapse wh...
Numerical modeling of elastomeric seismic isolators for determining force–displacement curve from cyclic loading
International Journal of Advanced Structural Engineering - Tập 11 - Trang 361-376 - 2019
The ideal performance of seismic isolating systems during the past earthquakes
has proved them to be very useful in protecting structures against earthquakes.
The cyclic loading experimental tests are an important part in the process of
completing the design of the isolators, yet they are very expensive and time
consuming. Using the accurate analytical modeling of hysteresis tests and
knowing the ...
Seismic behavior of a low-rise horizontal cylindrical tank
International Journal of Advanced Structural Engineering - Tập 10 - Trang 143-152 - 2018
Cylindrical storage tanks are widely used for various types of liquids,
including hazardous contents, thus requiring suitable and careful design for
seismic actions. The study herein presented deals with the dynamic analysis of a
ground-based horizontal cylindrical tank containing butane and with its safety
verification. The analyses are based on a detailed finite element (FE) model; a
simplified ...
An experimental study on response control of structures using multiple tuned liquid dampers under dynamic loading
International Journal of Advanced Structural Engineering - Tập 9 - Trang 27-35 - 2016
In this paper, the performance of multiple tuned liquid damper (MTLD) has been
investigated in mitigating the response of a structure under dynamic loading,
i.e., harmonic excitation. For comparative study, the responses of single-tuned
liquid damper (STLD) have also been considered. A set of experiments are
conducted on a scaled model of steel-structure-STLD and MTLD systems to evaluate
the perfo...
