Shell Concrete Structure Design and Construction 1 1 Introduction The ACI code defines a thin shell as a: “Three-dimensional spatial structure made up of one or more curved slabs or folded plates whose thicknesses are small compared to their other dimensions. Thin shells are characterized by their three-dimensional loadcarrying behavior‚ which is determined by the geometry of their forms‚ by the manner in which they are supported‚ and by the nature of the applied load.” Concrete shell

Grew from the Concrete” by Tupac Shakur‚ my personal takeaway from the poem is the importance of perseverance. To me‚ it seems that in this poem it alludes to hard work and proving any doubters wrong in the process and this can be seen by “Proving nature’s law is wrong it learned to walk without having feet” (3-4). One literary element that was evident in the poem was symbols. One symbol is clear in the very opening line “Did you hear about the rose that grew from a crack in the concrete?” (1-2) this

Both’’ I know why the caged bird sings’’ and’’ The Rose who grew from concrete’’ reflect on the subject of hope. Despite the similarities the subjects used by the poets to demonstrate the themes are quite different.

Chapter 1 INTRODUCTION 1.1 Background of the study Concrete is widely used in constructing buildings‚ houses and other structures‚ but in order to have a strong structure there are factors to be considered. One of which is compressive strength‚ this is important to the structure especially if it is a high rise building and will be used commercially. The compressive strength of a concrete is important especially to the column of a structure because it resists compression force. Columns must have
