The structural steel elements of buildings are normally not subjected to full design strength, under normal operation. Structural steel is a non-combustible material and its properties can be affected by elevated temperatures. The terrorist attack on multi-storey steel structure World Trade Centre in New York is worst event in the history, which resulted in tragic loss of lives. Therefore, high rise steel buildings must be able to resist high temperatures so that there is a minimum damage to the structure. The main purpose of this paper is to investigate the temperature effects on multi-storey steel building subjected to elevated temperature. In this paper, a study is made to investigate the effect of elevated temperature on structural elements of steel buildings. The main properties of steel that were found to change with an increase in temperature from 20 degree centigrade to 1400 °C are modulus of elasticity of steel, and yield strength of the structural steel. High grade steel, Fe410 was found to better resist the temperature changes as compared to Fe250. These results are expected to help the designers and planners in making appropriate provisions for providing a higher temperature resistance to the steel structures.Keywords

Most farmers in Northern Nigeria rely on conventional irrigation channels to transfer water from rivers, dams, lakes, or streams to their respective farmlands for irrigation. However, this method of water distribution is not without problems; seepage, evaporation, and transpiration are difficult to prevent, construction and maintenance of these channels take a significant amount of time, and maintaining a steady fall is relatively difficult. In general, the channel distribution system is much less efficient than a system based on pipes. Nonetheless, pipes are relatively expensive and often inaccessible for the riparian and other small-scale farmers in Northern Nigeria. This study aims to propose an alternative water distribution approach that will minimize water loss and deliver the water at a higher level using new (less expensive and readily available) material, which has been used to line water channels. After assessing different materials, a distribution system with a plastic envelope suspended from a taut wire was used, making it possible to accept water at a position, about 2 m, above ground level, and carry it over appropriate distances at minimum fall rates without losses. A means of discharging water from the envelope and distributing it over a cropped area was also developed, thus rendering the system resistant to problems associated with flooding of small basins.Keywords
