The Life Of Roses Family: Rosaceae Introduction: Rose is the topmost commercial cut flower crop in the international market. It is the most widely grown and traded cut flower. It is acclaimed as Queen/King of flowers. Roses can be cultivated on open land, but for cut flower production these are grown under controlled conditions of the greenhouse and the flowers exhibit the best quality attributes required for the market. The plants are perennial thorny bush. The present day rose (Rosa hybrida) combines all desirable qualities such as productivity, attractiveness of bud, fragrance, a variety of colours and forms of the typical species of Rosa. Cultivars: Red: Upper class, Passion, First Red, Grand Gala (thornless), Red Torch Yellow: Galileo, Royal Yellow, Taxi Pink: Upper Class Pink, Adamma, Billie Jean White: Peaceful Green: Dubai, Tendaji, R.chinesis viridiflora Blue: Applause (genetically engineered) Propagation: Commercially roses are multiplied by T-budding and...
STRUCTURAL ANALYSIS Structural analysis is necessary to find the internal forces developed in the members of the structures. The required internal forces for design are axial forces and moments. IS code permits the following methods of analysis: (a) Elastic Analysis (b) Plastic Analysis (c) Advanced Analysis (d) Dynamic Analysis. (a) Elastic Analysis . It is based on the assumption that - no fibre of a member has yielded for design load and stress is linearly proportional to strain. The analysis may be in 2 stages:- Stage 1 Order Analysis: It is based on the loads acting on undeformed geometry of the structure. Redistribution of 15% of peak moment is permitted by code. Stage 2-Second Order Analysis: It is based on the deformed (large deflection theory) shape of the structure. IS 800 permits use of amplification factors (as given under clause 4.4.3.2) instead of second order analysis. (b) Plastic Analysis : In this method it is assumed that when every fibre at a section reach...
