Desi n is an anal sis of trial sections. The stren th of each trial section is compared with the expected load effect. The load effect on a section is determined usin structural analysis and mechanics of materials. The strength of a reinforced concrete section is determined usin the conce ts tau ht in this class.

Show all our assum tions and work details. Pre are neat sketches showing the reinforcement and dimensions. Markin will consider rimaril neatness of resentation completeness and accuracy of results. You may get the HW points if you copy the solution from other students. However, you will have lost your chance in practicing the concepts through doing the HW. This will lead you to loosing points in the exams, which you could have gained if you did your HWs on your own. No late HWs will be accepted. Homework solutions will be
