The dual system shown below is comprised of a steel moment resisting frame and steel chevron braces. Note that the interior connection of the moment frame is a shear tab or simple pin connection. The wide flange (W-Shape column members, C1 and C2, are oriented for strong axis bending with geometric properties found in Table 1-1. The braces are Square HSS with geometric properties found in Table 1-12. Assume E 29,000 ksi for all members.

 

 

Use approximate analysis to find the maximum shear and bending moment in columns C1 and C2 as well as the maximum axial force in each brace, B1 through B4. Summarize your results in a table like the following:

 

What percentage of the total lateral load do columns C1 and C2 resist?

W18X158 —– Area = 46.3in^2 I=347in^4

HSS6x6x3/8 —- Area = 7.58in^2 I=39.5 in^4

HSS9x9x1/2 —- Area = 15.3in^2 I= 183in^4

The AB Charity is planning its annual campaign to raise money. This year three alternative methods are being considered: (i) street collections, (ii) a television advertising campaign and (iii) a directmail appeal. After using simulation to assess the risk associated with the alternatives the charity’s managers have opted for a direct-mail appeal. The direct-mail appeal will involve sending out 343 000 letters to selected people. To encourage donation these will include a free ballpoint pen displaying the charity’s logo and people not replying after three weeks will receive a reminder. While the fixed costs of the campaign and the cost of sending out each letter and reminder are known for certain the charity’s managers have had to estimate probability distributions for the following four factors: (a) The percentage of people who will reply to the first letter in the North (N), Central (C) and South (S) regions of the country, respectively. (b) The average donation of those replying to the first letter in each of these regions. (c) The percentage of people who will reply to the reminder in each of the three regions. (d) The average donation of those replying to the reminder in each of the regions. Probability distributions have been estimated for the different regions because their different economic conditions are likely to have a major effect on people’s propensity to donate to the charity. The cumulative probability distribution of net returns (i.e. the total value of donations less the cost of running the direct-mail appeal). It can be seen that there is approximately a 20% probability that the net returns will be negative, causing the charity to lose money. In the simulation the possible losses extended to nearly $150 000. The managers of the charity are keen to take action to reduce this risk, but are not sure where their actions should be directed? The numbers at the ends of the bars show what are thought to be the highest and lowest possible values for each factor. For example, the possible average donation in the North is thought to range from $2 to $17. (a) Identify the areas where risk management is likely to be most effective. (b) Create a set of possible risk management strategies that might reduce the risk of the charity losing money and increase its expected return.
