The frame below has wind load and dead as shown. Use w(Dead) = 6 kip/ft and w(Live) = 3 kip/ft, L = 30 ft and H = 15 ft. The beams and columns have modulus of elasticity E of 29000 ksi and moment of inertias I(beam) = 2000 in4 and I(column) = 800 in4. Similarly they have cross-sectional areas A(beam) = 20 in2 and A(column) = 25 in2. Consider that the wind can act in both horizontal directions. Determine: The...

Solve please. CMCE 2416 Elements of Structural Design - Concrete Assignment 4: Short Column with Axial Load Determine if a 10" x 10" tied column reinforced with 4 #5 longitudinal bars is adequate to carry an axial load of Pu = 118 kips. Design the ties. Concrete compressive strength is 4,000 psi and the yield strength of both the longitudinal bars and the ties fy = 60,000 psi.
Critical Buckling Load--Spring Connection The leg in (a) acts as a column which can be modeled as in (b), where the spring connection at the knee has stiffness k (torque/rad). Assuming the bones to be rigid, determine the critical buckling load. 2 Speed 00:27/08:09 info CC The critical load of a spring connection is: is a larger value than the pre-load state assumed to be a small angle approximation before buckling occurs found through the analysis of the FBD all...
help Deduce the equations for all the nodes and calculate the load to which each element of the structure is subjected. The system of equations must be presented in an orderly manner and correctly designated. Solve the system of equations manually for the maximum load. M=cte, maximum load, m_max = 10M. A.
A tie rod (1) and a pipe strut (2) are used to support a 50-kN load, as shown. The cross-sectional areas are A1 =650 mm2 for tie rod (1) and A2 = 925 mm2 for pipe strut (2). Both members are made of structural steel that has an elastic modulus of E=200 GPa. a) Determine the axial normal stresses in tie rod (1) and pipe strut (2). b) Determine the elongation or contraction of each member. c) Sketch a deformation...
m Review Learning Goal: To use the formula for the critical load, i.e., the Euler buckling load, for pin-supported columns to calculate various parameters of columns. A column is made from a rectangular bar whose cross section is 5.5 cm by 9.1 cm . If the height of the column is 2 m, what is the maximum load it can support? The material has E = 200 GPa and Oy = 250 MPa Express your answer with appropriate units to...
