In this paper, the rib beam bridge slabs were taken as research object. Static load and fatigue tests carried out on benchmark to determine ultimate capacity life of slabs. Then, slab was pre-damaged reinforced with polyurethane concrete. A test study performance. Based damage theory, reinforcement finite element models under different degrees established. The performance systematically studied...

The use of static load testing in optimising design and providing verification of suitability and constructability continues to be unsurpassed in the foundation industry. The utilisation of top load reaction testing appears to be that with which most European engineers are familiar, but a variation on this, which has become just as conventional in some parts of the world, is the use of bi-direc...

To investigate the bearing capacity of hollow Glass Fiber Reinforced Polymer (GFRP) pipe-concrete-steel tube composite long columns subjected to eccentrical compression load, 33 GFRP have been designed. The slenderness ratio (?), compressive strength concrete cube ( f cu ), eccentricity (e) and so on are main parameters. Based constitutive models for steel, confined concrete, numerical simulati...

The pile’s ultimate capacity or failure load must be computed by some criteria using load-settlement curve data gathered during the pile test. Many scholars have proposed several approaches for evaluating in past. This study compared different to predict piles with two lengths-to-diameter ratios embedded gypseous soil gypsum content of 60% under soaked and unsoaked conditions. Two types were us...

To develop a systematic review to evaluate, through the best scientific evidence available, the effectiveness of aerobic exercise in improving the biomechanical characteristics of tendons in experimental animals. Two independent assessors conducted a systematic search in the databases Medline/PUBMED and Lilacs/BIREME, using the following descriptors of Mesh in animal models. The ultimate load o...

retrofitting structures is an important issue. structural weakness may be due to changes in design codes or defects in implementation. adding structural floors to the existing structures may also lead to the need for strengthening and retrofitting. retrofitting is possible before the earthquake or may take place as rehabilitation of damaged members after earthquake. elements such as columns in ...

The mechanical behaviour and design of fixed-ended steel equal-leg angle section members subjected to axial compression are addressed in this study. First, the critical buckling is described. Experimental data on columns collected from literature then used for validation numerical (shell finite element) models, developed within commercial package ABAQUS. Validation performed by means comparison...

Ultimate bearing capacity calculation is one of the most important factor to design foundations in geotechnical engineering. In this paper, ultimate values were calculated with finite element and analytical methods compared. A case study Bozozuk (1972) article used for evaluations. On 30 September 1970, 600-ton weight concrete silo suddenly overturned failure. After failure, in-situ Vane shear ...

Due to structural degradation, the performance of concrete bridges may degrade with time and result in catastrophic consequences. A novel approach is developed for evaluating time-variant reliability multi-girder considering effects load-carrying mechanism redundancy. By three failure modes at both component system levels, a new indicator proposed quantitatively load elastic distribution plasti...
