Simplified code provisions can be used for the analysis and design of straight slab bridges. However, several studies question appropriateness simplified procedures skewed geometries. This paper provides practical insights to designer regarding effects skewness in reinforced concrete bridges by evaluating how more refined impact magnitudes resulting reinforcement layouts. The methods this study...

The test results described in Part 1 of this paper (Lee and Bruneau, 2008) on twelve steel built-up laced members (BLMs) subjected to quasi-static loading are analyzed to provide better knowledge on their seismic behavior. Strength capacity of the BLM specimens is correlated with the strength predicted by the AISC LRFD Specifi cations. Assessments of hysteretic properties such as ductility capa...

ABSTRACT: Recently, limit state design (LSD) in geotechnical engineering has been developed through LRFD in North America and Eurocode 7 in Europe. LRFD is an approach that estimates resistance by design model and that multiplies resistance factor by calculated resistance to reflect the uncertainty of materials and design models. Whereas, Eurocode 7 employs the partial resistance factor applied...

This paper presents a genetic algorithm model for the cost optimization of composite beams based on the Load and Resistance Factor Design (LRFD) specifications of the AISC. The model formulation includes the costs of concrete, steel beam, and shear studs. Two examples taken from the literature were analyzed in order to validate the model, to illustrate its use, and to demonstrate its capabiliti...

Material profil IWF C digunakan dalam Perencanaan atas gudang, software SAP20...

Supplementary cementitious materials (SCMs) and fillers play an important role in enhancing the mechanical properties durability of concrete. SCMs are commonly used self-consolidating concrete (SCC) mixtures to also enhance their rheological properties. However, these additives could have significant effects on viscoelastic Existing models for predicting creep drying shrinkage do not consider e...

The use of powerful numerical tools based on the finite-element method has been improving the prediction of the holding capacity of fixed anchors employed by the offshore oil industry. One of the main achievements of these tools is the reduction of the uncertainty related to the holding capacity calculation of these anchors. Therefore, it is also possible to reduce the values of the associated ...
