EGN5439 The Design of Tall Buildings Lecture 26 Analysis of a Shear Wall Find the shears and moments in a 20st0ry building s shear walls L A PrietoPortar 2008 1quot 4 i This lecture s problem is like this shearwall at a building in Coral Gables LeJeune and Valencia Find the shears and moments in the shear walls of a nonproportionate nontwisting building The typical floor plan of a 20story of ce building is shown on the next slide and the elevation of the building on the slide after that one Notice that the shear walls are oriented in the yaxis only to provide simplicity to the problem A real structure would have shear walls in both the X and yaxes Walls 3 enclose the elevator and stair cores Notice that all the shear wall thicknesses are a function of their location along the vertical portion of the building The wind pressure is assumed to be uniform for simplicity at a value of 15 kNm2 throughout the building s height Each floor is 35 m high and all floors have the same height

L kht0 m n 56MO A29Yu1m260m4 12 12 12 12 Step 2 Determine the ratios k and Q of the inertias Iii of each wall Recall that the total external shear Q and the total external moment M at the story level i will be distributed between all the walls at that level in the ratio of their flexural rigidities E1 The resulting shear and moment in any wall j at that level i is given by jS Qi and M l M l where E1 E1 0 Q EIl 1 EIl E1 E1 0r EIl 1 E1 EIji is the flexural rigidity of the wall j at the level i and HE i represents the summation of the exural rigidities of all the walls at level 139 Since the modulus of elasticity E is the same for all the walls it is only required to find the ratios of the moments of inertia I s The ratio of the moments of inertia between two levels of a same shear wall is the parameter k Thus k is the ratio of a particular wall s stiffness on a speci c floor to the value of the stiffness of that entire floor Therefore the parameter k for each wall j at floor x is dependent of the inertias of the walls above and below oor x This is expressed as above below above Xj below Xj kxj n kxj n above below Zia Zia where lax and bej are the inertias of the wall j just above and just below the floor X For example Wall 1 at the 14th floor j 1 andx 14 above 8 5 kabove X above 36 x 20 am 391 85 2105260 21x j1 below kbelow Ixj klbfllow L x 1283105260 20 below 2 i1 All the other values for all the other two shear walls 2 and 3 at this transition floor 14 are also obtained in the same manner The change in the parameter k for Wall 1 at the 13 to 14th floor transition is below above Akxj Ak141 kxj kxj 044036 008 All the other k parameters are found for the this Wall 1 and then for Walls 2 and 3 All the values of k are tabulated on slide 12 along With other parameters we still need to calculate Finally a check can be made of k at each floor level through this relation 2kg mm 1 The next ratio is p which expands the value of k to the two floors at a transition of stiffness like the slab between the 13th and 14th floors It is the stiffness of the floor above or below to the combined stiffness of both oors The ratio p is defined by these two relations above below above Xj below Xj px above below and pxj above below 96quot 96quot X X For example the value of p for Wall 1 at 14th floor slab is above above Ixj above xj Iabove Ibelow p14 1 8

columns on the leeward side have an increase of compression This is the same model we just saw for the stud wall Because the tall building is subject to this force couple it de ects primarily in exure bending Therefore a shear wall is perhaps a misnomer since or model stud wall panel is primarily in uenced by the tension on one side and the compression on the other side also creating a moment Hence our shear wal is really a short and stubby exural wall All shear walls behave like this including the large and heavy reinforced concrete shear walls we use for our tall buildings in our cities
