A gazebo is planned to be constructed in a community park as an additional shelter for visitors from sunshine and rain.
A gazebo is planned to be constructed in a community park as an additional shelter for visitors from sunshine and rain. The gazebo is supported by 4 units of rectangular steel rods - each with cross-sectional area of 7200 mm2 and slendemess ratio of 0.026. The modulus of elasticity of the steel rods is 200GPa and the maximum allowable stress, σy is 233MPa. a. Recommend the maximum effective length of the rectangular steel used to support the gazebo when the safety factor of 1.67 and the support condition of the columns being one fixed end and one pinned end. Justify your answer. b. A new design suggestion for cost savings indicated that the cross-sectional area be reduced to 3750 mm2 with length, L of 1.8 m and moment of inertia, / of 1.758×106 mm4. Evaluate whether the columns will fail if the support condition of the columns of both ends fixed is employed. Justify your answer.
