Preparation and Properties of Blends of Thermoplastic Polymer with Thermoplastic Starch
Abstract: Problems in making biodegradable plastics are incompatible between hydrophilic/polar and hydrophobic/non-polar ingredients. Ingredients like compatibilizers were added to improve the compatibility between the two ingredients. The purpose of this study was to determine the effect of thermoplastic potato starch (TPS) content and two compatibilizers (maleic anhydride, MA, and dibutyl maleate, DM) on melt flow behavior, mechanical features (tensile, bending, and Izod impact test), phase morphology, thermal behaviors (DSC, and TGA/DTG), …

Application of flux cored arc welding (fcaw) without pre-heating for heavy structures in ship building fabrication & construction of heavy offshore structural steels
Abstract: In fusion welding processes, the reason often given to explain the need for preheating, controlling the inter pass temperature (in multi-pass welds), and post-weld heat treatment (PWHT) is to reduce the risk of residual stresses and it can be removed by heating weldment in the heat affected zone (HAZ). Cold cracking is a hydrogen embrittlement phenomenon, often referred to as hydrogen induced cracking or HAZ cracking. During the construction and …

Flood Resistant Houses
Abstract: Unusual high stage of river is called flood. In flood, the water level rises to an extent in which water starts spilling over the bank and spreading to the flood plains. The frequency and intensity of floods has intensified in the country over the years primarily due to encroachment of flood plains because of obvious advantages of water supply and irrigation. Flood causes extensive damage to infrastructure, the economy and …

Managerial Strategy for Controlling Hazards in Building Construction Projects
Abstract: The construction site is always associated with man power intensive and hazardous work environments. Even today, controlling/minimizing hazards at any construction site is a challenging task. Hazard is defined as an inherent property of a substance or an occurrence, which has the potential to cause loss of injury to property, person or environment. The different sources of hazard at construction site includes physical, chemical, biological, natural, electrical and radiant energy …

Safety Issues with Tower Crane and Remedial Measures
Abstract: Tower cranes are the focus of execution on today’s typical building construction sites. Tower crane has to hoist and transport a variety of loads near and above people, under crowded conditions, occasionally with overlapping work zones, and often within time, budget, and labor constraints. This leads to the safety risk on sites that are intrinsically hazardous. This paper identifies the major factors affecting safety of tower-crane and evaluates the degree …

Time Overrun Causes in Public Construction Projects in Saudi Arabia: Contractors’ View
Abstract: The time schedule in construction projects is one of the prime measures for project success. However, the construction industry worldwide is full of projects that were completed with significant time overrun. This problem is critical and has negative effects on construction parties in terms of growth in adversarial relationships, mistrust, litigation, arbitration and cash flow problems. This study aims at identifying the time overrun causes in public construction projects in …

Comparative Study of Flat Slab and Conventional Slab Structure Based on Seismic Behaviour and Cost Effectiveness
Abstract: Flat slab recent earthquakes in which many concrete structures have been severely damaged or collapsed, have indicated the need for evaluating the seismic adequacy of buildings. About 60% of the land area of our country is susceptible to damaging levels of seismic hazard. We can’t avoid future earthquakes, but safe building construction practices can certainly reduce the extent of damage and loss. As being one of the special reinforced concrete …

Analysis of Proposed Diagrid Geometry Using Golden Ratio in Non-linear Regime of Material
Abstract: Lateral loads are critical in the design of high-rise structures. The buildings need to have high stiffness and must be able to resist lateral deformations and torsional rotations without having discomfort to the user. Diagrid structural system is one of the systems used in resisting lateral forces. In this study, diagrid geometry is generated using the ‘Golden Ratio’ concept and used to model 40, 50, and 60 story structures. Two …
