Development of Innovative Load Transfer Mechanism to Reduce Hurricane-Induced Failures in New and Existing Residential Construction

Implicit in current design practice of minimum uplift capacity, is the assumption that the connection's capacity is proportional to the number of fasteners per connection joint. This assumption may overestimate the capacity of joints by a factor of two or more and maybe the cause of connection failures in extreme wind events. The current research serves to modify the current practice by proposing a realistic relationship between the number of fasteners and the capacity of the joint. The research is also aimed at further development of non-intrusive continuous load path (CLP) connection system using Glass Fiber Reinforced Polymer (GFRP) and epoxy. Suitable designs were developed for stud to top plate and gable end connections and tests were performed to evaluate the ultimate load, creep and fatigue behavior. The objective was to determine the performance of the connections under simulated sustained hurricane conditions. The performance of the new connections was satisfactory.

Impact of the Afghan refugees on Pakistan

There was a massive influx of Afghan refugees into Pakistan following the Soviet military intervention in Afghanistan in December 1979. An attempt has been made here to analyze the political, ethnic, economic and social ramifications of the Afghan refugees on Pakistan. Among the consequences of the presence of Afghan refugees are: 1. A heavy burden on Pakistan's resources on account of sustaining the 2.8 million Afghan refugees 2. Friction between Afghan refugees and the Pakistani population, due to land, employment, animal grazing-pasture and water-supply disputes, and 3. A direct threat to Pakistan's internal security and political stability, which is made evident by numerous violations of Pakistan's western borders by Soviet-Afghan air and ground forces in pursuit of the refugees and Afghan Mujahidin. The political talks on the Afghan crisis are deadlocked on the question of a Soviet troop withdrawal. The Soviets and Afghans insist on the stoppage of foreign support to the Afghan counterrevolutionaries. The refugees in Pakistan will not return to their homes unless they are insured a safe and honorable life by the Afghan government.
