A two-story building is modeled as shown in the figure. The columns have an identical rigidity k1 = k2 = 3 and the masses of the two stages are also identical m1 = m2 = 1 Assuming that a wind load F(t) = sin(t) is applied to each floor (Do not take into account the effect of the weights masses in the static state) a) Write the two differential equations of each of the masses m1 and m2. b) Assuming...
A two-dimensional two-pinned portal frame ABCDE is pinned to rigid supports at positions A and E, and a concentrated couple of 350 kNm acting clockwise is applied at C as shown in Figure Q3. All members of the portal frame are made from the same steel section. 350 kNm 6 m EI CONSTANT FOR ALL MEMBERS 6 m 4 m Fgure Q3 Determine, using methods incorporating strain energy where appropriate. the magnitude and direction of the vertical and horizontal reactions...
REINFORCED CONCRETE DESIGN CLASS PROJECT The structural floor plan of a three-story (ground floor, two suspended floors, and a roof office building is shown on the next page. The floor includes one and two way solid slabs. The new building will be located in Sharjah, UAE. The floor systems consist of one-way and two-way solid slabs supported by beams running in both directions as shown in the floor plan. The design loads for the floor (in addition to the self-weight)...
A rigid, uniform, horizontal bar of mass m1 and length L is supported by two identical massless strings. (Figure 1) Both strings are vertical. String A is attached at a distance d<L/2 from the left end of the bar and is connected to the ceiling; string B is attached to the left end of the bar and is connected to the floor. A small block of mass m2 is supported against gravity by the bar at a distance x from...
The single-story unbraced frame shown below is subjected to dead load, roof live load, and wind load Figure 1 shows the results of a first-order analysis relative to the columns of the frame. The axial load and end moment (also equal to the maximum moment in the column) are given separately for the different load cases (i.e., dead load, roof live load, and lateral wind load). All vertical loads are symmetrically placed and contribute only to the Mnt moments (i.e.,...

A 3 m rigid bar AB is supported with a vertical translational spring at A and a pin at B The bar is subjected to a linearly varying distributed load with maximum intensity g Calculate the vertical deformation of the spring if the spring constant is 700 kN/m. (ans: 21.43 mm) 2. A steel cable with a nominal diameter of 25 mm is used in a construction yard to lift a bridge section weighing 38 kN. The cable has an...
I need Summary of this Paper i dont need long summary i need What methodology they used , what is the purpose of this paper and some conclusions and contributes of this paper. I need this for my Finishing Project so i need this ASAP please ( IN 1-2-3 HOURS PLEASE !!!)
