This paper aims to show the application of site-specific response spectra in analysis buildings that are supported by lightly reinforced precast concrete walls. Previous surveys on load-bearing walls multi-storey low-to-moderate seismic regions have found many existing with a connection reinforcement ratio less than wall ratio. When these subjected reversed cyclic loads, lateral is typically co...

Lattice boom used on the crawler crane are welded by slender high strength steel tubes. Many studies show that actual bearing capacity of high-strength tubes is higher than stability calculated according to specification. To obtain and apply it engineering practice, a series axial loading tests carried out two kinds 20Mn2 S890 their damage load. By handling test data, coefficient fitting correc...

The reliability index is an important reliability parameter that is necessary for the development of reliability-based geotechnical design. Both the factor of safety (FS) and the reliability index (β) represent safety margin of structures against either failure or limit state. In this study, the reliability index is analyzed and evaluated in reference to the factor of safety currently adopted i...

Grouped and single pile behavior differs owing to the impacts of the pile-to-pile interaction. Ultimate lateral resistance and lateral subgrade modulus within a pile group are known as the key parameters in the soil-pile interaction phenomenon. In this study, a series of experimental investigation was carried out on single and group pile subjected to monotonic lateral loadings. Experimental inv...

Most of the laboratory tests investigated the flexural performance of un-preloaded or undamaged RC beams strengthened with CFRP composites. However, in engineering applications, the structural member must carry a certain load or damage. There is a lack of systematical investigations on the effects of preload or damage level on the flexural load-carrying capacity of CFRP-strengthened RC beams. T...

Abstract Recently, new materials and methods have been implemented to improve the performance of reinforced concrete columns. This paper studies experimentally behavior high-strength columns, with additional internal confinement using hexagonal chicken wire mesh (HCWM) enhance ductility, energy absorption, ultimate strength reduce brittleness traditional Eight double-ended one-third-scale colum...

In the present study, a new method for retrofitting reinforced concrete beam is introduced in which steel-concrete composite jackets containing steel fiber is used. For this purpose, 75% of the peripheral surface of reinforced concrete beams was initially reinforced using steel plates and bolts, and steel fiber reinforced concrete was used between the steel plates and the peripheral surfaces of...

Current innovative lateral load carrying systems for tall buildings are those in which the lateral drift is limited to an allowable value without considerable influence on economy. This aim is achieved by using special systems capable of using maximum stiffness and strength capacity of individual structural elements. An effective structural solution in this respect is the use of outrigger brace...
