The aim of this research is to examine the market potential for wood plastic composite (WPC) products in the highway construction sector in place of nonrenewable materials (e.g. virgin plastic and steel) and preservative-based products (treated wood). State-level transportation officials indicate that the majority of highway construction purchases are conducted by highway construction contracto...

be from pipe and connection breaks rather than structural failure of distribution reservoirs (as long as the reservoirs have been designed for lateral loading). Most of the examples of storage tanks and distribution reservoirs impacted by the 1994 Northridge and 1995 Hyogo-ken Nanbu earthquakes appear to have been of steel construction rather than of reinforced concrete or prestressed concrete ...

One application, only in-situ soil mixing (or deep mixing method, DMM) is becoming increasingly common as an economical construction method for temporary support of deep foundation excavations and is also used in the construction of permanent retaining walls. Steel beams placed into the fresh soil/cement are generally used as the primary structural support, later supplemented with bracing or ti...

Composite RCS building frames integrate reinforced concrete columns with structural steel beams to provide an efficient solution for the design and construction of earthquake-resisting structures. In this paper, an optimization framework is developed for performance-based seismic design of planar RCS moment resisting frames. The objective functions are defined as minimizing the construction cos...

The potential of buckling in compressive members has been considered as a disadvantage when using steel members in the construction industry. In spite of the progress made in this regard, buckling is still considered as a challenge in the analysis and design of compressive steel structural members. Such a challenging phenomenon can be controlled by strengthening of compressive members. Stiffene...

This paper presents an investigation of the fatigue crack growth (FCG) behavior at fastener holes in a high strength steel. 30CrMnSiNi2A, before and after a cold-expansion process. The fatigue life of coldworked specimens was signitkantly increased compared to non-wldworked ones and increased the !O\ver applied stress level. From a study' nf the residual stress distribution near the edgc of the...

Carbonitriding of four types of steels, namely, low carbon steel (LCS), medium carbon steel (MCS), low alloy steel (LAS) and high alloy steel (HAS) was achieved using cyanide salt bath heat treatment process. The steels, after preheating, were heated in a diesel fired salt bath heat treatment furnace and then quickly quenched in different media including air, oil and brine. The heat treatment p...

Fly ash and granulated blast furnace slag (GBFS) are major by-products of thermal and steel plants, respectively. These materials often cause disposal problems and environmental pollution. Detailed laboratory investigations were carried out on cement stabilized fly ash-(GBFS) mixes in order to find out its suitability for road embankments, and for base and sub-base courses of highway pavements....

Stud welding is a process used in the construction industry to anchor concrete slabs to underlying steel substructures . This process is highly repetitive and, thus, a good candidate for automation. A robotic device, the Studmaster , has been developed which will automate stud welding currently done in the construction of industrial buildings. This machine, currently controlled by a microcomput...

 In recent years, high-rise construction has been rising. A big challenge for engineers and executives in the construction of these structures is the stability of the structures against earthquakes. And this requires the development of appropriate arrangements for structures under lateral system and are braced system. And this requires the development of appropriate arrangements for structures ...
