Size Of Firms

If formal institutions of contract governance are absent or ineffective, traders try to substitute relational governance based on norms and sanctions. However, these alternatives need good information and communication concerning members’ actions; that works well only in relatively small communities. If there are fixed costs, the market has too few firms for perfect competition. The optimum must be a second best, balancing the effectiveness of contract governance and dead-weight loss of monopoly. This chapter explores this idea using a spatial model with monopolistic competition. It is found that relational governance constrains the size of firms and can cause inefficiently excessive entry, beyond the excess that already occurs in a spatial model without governance problems. Effects of alternative methods of improving governance to ameliorate this inefficiency are explored.

AbstractThe indirect effects of military spending on security are stronger and more important than its direct effects, and its long run impact more telling than its short run impact. In the short run, military spending can be a source of both physical security and economic stimulus. In the long run, it can be counterproductive in terms of physical security and will be a dead weight on the economy. How a society’s productive resources are deployed, as between military spending and more economically productive activities, sets it on a long-term course with powerful implications for the ability of its economy to do what it is supposed to do – provide for the material well-being of the population as a whole. The mechanism by which the extensive and extended diversion of productive economic resources to economically unproductive military spending drags an economy down is analyzed. Furthermore, it is possible to use properly structured international and domestic economic relationships in place of threats or use of military force to increase national and international security, while at the same time enhancing, rather than degrading, economic wellbeing. Three principles for structuring such a “peacekeeping economy” are set forth.

Strain Responses

Intumescent mat materials in catalytic converters undergo chemical reactions that lead to material property changes and volume expansion during heating processes. Dead weight (load control) and displacement control compression experiments have been performed to explore static and transient stress-strain responses. The apparatus and methods for both experiments are described. The experimental results together with a strain decomposition procedure yield a master curve that can be employed for constitutive modelling.

The Bubble Deck technology developed in Europe makes use of high-density polyethylene hollow spheres to replace the ineffective concrete in the centre of the slab, thus decreasing the dead weight and increasing the efficiency of the floor. Concrete is good in compression and hence is more useful in the compression region than in the tension region. The reduction in concrete can be done by replacing the tension zone concrete. Keeping the same idea in mind, an attempt has been made to find out the effectiveness of plastic bubbles by replacing concrete in the tension zone of Ordinary Portland Cement Concrete (OPCC) and Geopolymer Concrete (GPC) beam. Geopolymer Concrete does not form calcium- silicate-hydrates (CSHs) for matrix formation and strength like OPCC but utilizes the polycondensation of silica and alumina precursors to attain structural strength. In this project, M25 concrete mix is used to prepare both OPCC and GPC beams. The trial mix is tested for compressive strength. Flexure test is done is done for 28 days of curing of the beams. This paper presents the results of the experimental investigations carried out to determine and to compare the flexural behaviour of geopolymer concrete (GPC) beams with conventional concrete beams of same grade. The beams were tested under two point monotonic loading. Performance aspects such as load carrying capacity, first crack load, ultimate load, load-deflection behaviour, moment-curvature behaviour, crack width, crack spacing and the modes of failure of both types of beams were studied. The test results showed that the geopolymer concrete exhibits better performance compared to conventional concrete of same grade.

Abstract: This study examines the composite structure that is increasing commonly in developing countries. For medium-rise to high-rise building construction, RCC structures is no longer economical due to heavy dead weight, limited span, low natural frequency and hazardous formwork. The majority of commercial buildings are designed and constructed with reinforced concrete, which largely depends on the existence of the constituent materials as well as the quality of the necessary construction skills, and including the usefulness of design standards. Conventional RCC structure is not preferred nowadays for high rise structure. However, composite construction, is a recent development in the construction industry. Concrete-steel composite structures are now very popular due to some outstanding advantages over conventional concrete and steel structures. In the present work, RCC and steel-concrete composite structure are being considered for a Dynamic analysis of a G+25-storey commercial building of uniform and optimized section, located at in seismic zone IV. Response Spectrum analysis method is used to analyze RCC and composite structure, CSI ETABS v19 software is used and various results are compared such as time period, maximum storey displacement, maximum storey stiffness. Maximum storey shear and maximum stoey overturning moment.

Cover concrete quality is very important for marine structures, which determines the beginning time of reinforcement corrosion and the life of the structure. The very early age continuous moisture keeping is essential for cover concrete properties develop; otherwise the long-term performance will be reduced heavily. There are many moisture keeping curing methods, but the drawbacks of traditional curing methods make them confined to use in marine environment concrete structures. A kind of moisture keeping membrane which can absorb and hold 100～5000 times of dead-weight water, and impede water evaporating outside with polyethylene film. The results of mercury intrusion porosimetry test and scanning electron microscope show that the new curing product can improve the concrete density decrease the connection degree of pores and the quantity of harmful pores content. Compared with other product on sales, the wet-keeping time can be adjusted and can be used repeatedly and continuously are the distinguishing features, which make it popular in some marine projects.
