This paper presents the development of a CFRP system for strengthening and repair of steel bridges and structures. The research program included development of the strengthening system, investigation of the behavior of strengthened bridges and special structures, and detailing requirements. Based on the research comprehensive guidelines including structural detailing are provided. This paper de...

Local strength of friction stir (FS) welds and FS processed aluminium alloys in heat treatable aluminium alloys is dominated by precipitation hardening. Strengthening due to stored dislocations is generally limited to 40MPa, and grain size strengthening is generally less than 10MPa. Local crystallographic texture can cause yield strength variation on the order of 5%. Published models for streng...

Objectives: A helpful functional exercise that tends to correct postural unevenness and attempts re-establish lumbopelvic mechanics is beneficial for patients with impairment. This study evaluates the effects of right sidelying respiratory left adductor pull back on improving hip biomechanics in participants a tendency stand side. Methods: total 30 subjects (6 females 24 males) Mean±SD age 28.5...

This work deals with the effect of 0.67 wt% Gd addition on microstructure and tensile properties Mg–4Al–5RE (where RE represents La–Ce mischmetal) alloy produced by sand casting (SC), permanent mold (PMC), high-pressure die (HPDC). The results show that could refine grains, but its efficiency decreases increasing cooling rate due to shifting from SC PMC finally HPDC method. Meanwhile, acicular ...

Economists know how to calculate optimal prices for electricity transmission. These are rarely applied in practice. This paper develops a thirteen node model, based on the transmission system in England and Wales, incorporating losses and transmission constraints. It is solved with optimal prices, and with uniform prices for demand and for generation, but re-dispatching to take account of trans...

A number of attitudinal expressions are identified and analyzed using dependency based syntactic analysis. A claim is made that attitudinal loading of lexical items is dynamic rather than lexical and that attitudinal loading of individual lexical items is acquired through their use in attitudinally loaded structures.

In th is paper I introduce a contrast between homomorphic and non-homomorphic ascript ions of informational content to representations. In the former case there is a mapping from the parts of the representation onto the constituents of the content. In the l a t t e r case, there is not; some of the constituents of the content are set t led bj background factors. I contrast th is d i s t i nc t ...

Auditory icons – or environmental sounds – have the potential to convey information by non-verbal means quickly and accurately. In addition, human listeners are quick to determine many qualities of an auditory object, such as location, distance, size, and motion, from acoustics of the signal. An experiment tests these two coupled assumptions in a controlled laboratory context. Stimuli consisted...

Re-life of aged load-bearing structures may be more efficient and economical than complete re-building. Nowadays, the strengthening an RC structure can designed using non-linear FE analysis, taking a realistic structural behaviour into account. Within current article, this process is demonstrated in connection with monolithic slab. The slab must strengthened due to change function which increas...
