Abstract:

Includes bibliographical references.<br>In the design of many engineering components subjected to cyclic or repetitive loading,fatigue is an ever-present challenge. The engineer often endeavors to design the structural or component system in such a way that the cyclic stresses are below a particular fatigue limit, or, in fracture mechanics terms, at stress levels below threshold. In the Paris formulation, fatigue threshold, Δҝₜₕ, may be regarded as that value of cyclic stress intensity below which fatigue crack growth does not occur. For a particular material and environment, this threshold va

Abstract:

The LISA Pathfinder geodesic explorer mission for gravitational wave astronomy aims to measure a residual differential acceleration noise approaching the femto-m/s^2/Hz^1/2 levels needed for eLISA. This measurement is complicated by a large, roughly nm/s^2, stable differential gravitational acceleration that must be actively compensated in order to hold the test particles centred inside an orbiting apparatus. The actuation force applied to compensate this effect introduces a dominant source of force noise in the mission noise budget. To suppress this noise source and avoid actuation instabili

A novel torsion pendulum thrust test stand for micro-Newton-scale spacecraft thrusters is described.

The design and testing of a gas-dynamic calibration thruster is included. This thruster is fully self-contained on the pendulum arm, with no external wires or feedlines connected to the device and impacting the dynamic response of the underlying pendulum. Initial calibration results are shown. Zero drift and hysteresis are present in the results, evidenced by a co

Abstract:

Many theories associated with quantum gravity, such as string theory, predict violations of inverse square law (ISL) of gravity at sub millimetre distances. To search for such experimental signatures we developed a magnetically levitated cryogenic torsion balance, the SSTB, and a set of masses with modulated density across their surfaces. The lateral force has to be measured as one mass is moved in front of the other with a micropositioner without any electrostatic shield between them. The expected Newtonian and electromagnetic forces have been studied to optimise the design of the masses. The

Abstract:

Skador och slitage på brokonstruktioner av betong beror på tösalter, armeringskorrosion och frostcykler i kombination med ökande trafiklaster. Den i särklass vanligaste reparationsåtgärden för dessa typer av skador är att göra en pågjutning. Metoden går ut på att först avlägsna det skadade eller dåliga betongskiktet innan en ny betong pågjuts. För att bedöma hur bra ett pågjutningsarbete är behöver vidhäftningen mellan den nya pågjutningen och gamla betongen fastställas. Den mest använda metoden för detta syfte är s.k. dragprovning som bestämmer draghållfastheten i vidhäftningen. I praktiken ä

Simulating the non-linear response of reinforced concrete (RC) buildings subjected to a sequence of input earthquake records, is an extremely complex concern in the field of the Earthquake Engineering.

In previous decades, considerable amount of numerical and experimental studies have been conducted, but more researches are needed in order to confirm a better understanding of the concept of seismic

Structural wood design standards recognize lateral torsional buckling as an important failure mode, which tends to govern the capacity of long span laterally unsupported beams.

Within this context, the present study reports an experimental and computational study on the elastic lateral torsional buckling resistance of wooden beams. The experimental program consists of conducting material tests to determine the longitudinal modulus of elasticity

Therefore a research project was undertaken to investigate the structural behaviour of compact cold-formed steel lipped channel beams subject to inelastic local buckling and yieldi

This type of construction is common in Australia, the USA and Europe. In Australia plasterboard is commonly used in external walls with brick veneer as the outer skin of buildings. Plasterboard, however, is considered as a non-structural material and in the design of the studs in wall frames

Abstract:

Une solution innovante de poutre mixte acier-béton a été développée en tenant compte des problématiques de résistance au feu et de montage sur chantier. La poutre est composée d'une partie métallique en U connectée à une partie en béton armé. En phase de construction, la poutre métallique supporte la dalle et constitue un coffrage pour la retombée en béton armé. La poutre en U résiste aux charges de construction sans système d’étaiement temporaire. Lors du coulage du béton, la poutre en acier est remplie en même temps que la dalle, ce qui permet un gain de temps considérable sur chantier. En p

The measurement is based on the relationship between the fiber-optic strain and interferometric light intensity which is derived by using the photo-elastic theory and Mach-Zehnder interferometry. We emphasized how to increase effects of that the strain of fiber optic induce by the host structure with shorter bonded length of the fiber optics. The case of Mach-zehnder in

Abstract:

碩士<br>逢甲大學<br>土木工程學系<br>107<br>Cross Laminated Timber (CLT) is a popular new construction material in Europe and America. CLT has some advantages such as less carbon emission during production, renewable and can be pre-fabricated, and can be used in walls, roofs or ceilings. When CLT is subjected to out of plane loadings, the failure of the panel depends on its weakest rolling shear capacity. In order to get the data for architectural design, we have to do research and analysis about the rolling shear capacity of wood. The purpose of this research is to develop a simple and effective method to

Abstract:

The torsion test was evaluated as a method for determining the shear strength of full-size structural lumber. The evaluation involved an experimental length study, an experimental depth study, and a finite element study. The length study consisted of fifty nominal 2x4 specimens, ten specimens for each length, and ten American Society for Testing and Materials (ASTM) shear blocks. One 14 foot long board yielded one specimen for each length: (a) 21.0", (b) 28.5", (c) 32.0", (d) 35.5", (e) 39.0", and (f) an ASTM D143-94 shear block. The statistical analysis revealed no evidence that the length af
