Load bearing design

Trends of Civil Engineering Load bearing structure by P. Jagadesh Confined masonry (CM) is a construction system consisting of load-bearing masonry panels that are confined with cast-in-place reinforced concrete tie columns and beams. Due to satisfactory seismic performance, CM has become the predominant low-rise residential construction system in several areas around the world. However, in developing regions, the use of substandard materials, details and construction practices may result in inadequate performance as highlighted in the 2010 earthquakes in Haiti and Chile. In the aftermath of an earthquake, households are often reluctant to reoccupy their dwellings due to concerns about safety of structures. If feasible, preventive strengthening or structural repair (post-hazard), to complement to temporary sheltering, are realistic options to respond to the pressing need for shelter on a large scale, since reconstruction poses greater barriers of cost and time. However, there is little knowledge on whether strengthening and repair can realistically improve the seismic behavior of a CM dwelling structure, especially using on text-sensitive techniques with locally available (and often relatively low-quality) materials. Addressing this knowledge gap is important to form pre- as well as post-hazard planning and decision making for hazard mitigation and disaster recovery. The goal of this research is to contribute to filling this gap by investigating whether it is feasible to strengthen (pre-hazard) or repair (post-hazard) substandard CM walls using context-sensitive materials and practices, and make them safe, hat is, offering a performance comparable. It was built with acceptable-quality materials and seismic details. Supporting experimental evidence is based on in-plane cyclic tests on six full-scale CM wall specimens (including control, strengthened and repaired specimens) built with substandard materials (e.g., concrete with cylinder compressive strength in the range of 9 - 14 MPa) and seismic details (e.g., open stirrups with relatively large on-enter spacing).

Soil Cement by K. Eswara Ajithvar

Soil-cement is a highly compacted mixture of soil/aggregate, portland cement, and water. Soil-cement differs from Portland cement concrete pavements in several respects. One significant difference is the manner in which the aggregates or soil particles are held together. A Portland cement concrete pavements mix contains sufficient paste (cement and water mixture) to coat the surface area of all aggregates and fill the void between aggregates.

In soilcement mixtures, the paste is insufficient to fill the aggregate voids and coat all particles, resulting in a cement matrix that binds nodules of uncemented material. It is widely used as a low-cost pavement base for roads, residential streets, parking areas, airports, shoulders, and materials-handling and storage areas. Its advantages of great strength and durability combine with low first cost to make it the outstanding value in its field. A thin bituminous surface is usually placed on the soil-cement to complete the pavement.

The cost of soil-cement compares favorably with that of granular-base pavement. When built for equal load-carrying capacity, soil-cement is almost always less expensive than other low-cost pavements. Economy is achieved through the use or reuse of in-place or nearby borrow materials. No costly hauling of expensive, granular- base materials is required; thus both energy and materials are conserved. The major engineering benefits of cement stabilization are increased strength, stiffness, better volume stability and increased durability.

The improvement of the unconfined compressive strength (UCS) of LSC composite was also evaluated. As regards the application aspect, the results shows that cement mixed lateritic soils are suitable for base course construction. The investigation also shows that increase in UCS was attributed to the cement hydration within soil mass, resulting in the formation of reaction products as analyzed by XRD. It was also found that UCS was proportionally increased with the amount of the major reaction products such as calcium silicate hydrate (CSH). They used the Portland cement is a popular additive for stabilization. They carried out unconfined compression test and UCS of composite soil cement was determined at various curing ages. From this they observed that UCS increased with increasing cement content as well as with increasing time of curing.A quantitative assessment of soil mineral composition was performed using X-RAY diffractometer, XRD, PHILIPS X’Pert MPD, Netherlands.

Blast Resistant Building by B. Sruthi

The increase in the number of terrorist attacks especially in the last few years has shown that the effect of blast loads on buildings is a serious matter that should be taken into consideration in the design process. Although these kinds of attacks are exceptional cases, man-made disasters; blast loads are in fact dynamic loads that need to be carefully calculated just like earthquake and wind loads.

The objective of this study is to shed light on blast resistant building design theories, the enhancement of building security against the effects of explosives in both architectural and structural design process and the design techniques that should be carried out. Firstly, explosives and explosion types have been explained briefly. In addition, the general aspects of explosion process have been presented to clarify the effects of explosives on buildings. To have a better understanding of explosives and characteristics of explosions will enable us to make blast resistant building design much more efficiently. Essential techniques for increasing the capacity of a building to provide protection against explosive effects is discussed both with an architectural and structural approach.

Damage to the assets, loss of life and social panic are factors that have to be minimized if the threat of terrorist action cannot be stopped. Designing the structures to be fully blast resistant is not an realistic and economical option, however current engineering and architectural knowledge can enhance the new and existing buildings to mitigate the effects of an explosion.

The main target of this study is to provide guidance to engineers and architects where there is a necessity of protection against the explosions caused by detonation of high explosives. The guidance describes measures for mitigating the effects of explosions, therefore providing protection for human, structure and the valuable equipment inside. The paper includes information about explosives, blast loading parameters and enhancements for blast resistant building design both with an architectural and structural approach. Only explosions caused by high explosives (chemical reactions) are considered within the study. High explosives are solid in form and are commonly termed condensed explosives.

Hydronic Pavement Heating System for Sustainable Ice-Free Roads by A. N. V. Ravindra

Hydronic pavement heating is an energy efficient heating system that uses tubing to run a hot liquid beneath the pavement. Hydronic pavement is an alternative method for de-icing of roads. A hydronic pavement (HP) could be more environmental friendly than traditional de-icing methods such as salting and mechanical crushers. The hydronic pavement system consists of embedded pipes in the pavement structure, with a fluid as energy carrier to melt the snow layer which is deposited on the pavements.

Winter road maintenance swallow’s 30 percent of state department of transportation maintenance budgets nationally, according to the Federal Highway Administration in United States of America. In 2016, the consumption of salt and sand used for winter maintenance of roads was around 0.6 and 1.7 million ton in Scandinavia located in Denmark. Driving on a slippery road pavement could be unsafe and dangerous. The situation might get even harsher in some particular sections of the road like slopes, curves and bridges. To mitigate the slippery conditions, a well-known method is to spread out salt and sand on road surfaces. A negative effect of spreading salt and sand is the polluting effect of the surrounding environment along the road and nearby water bodies.
