Max inlet flow rate = 870 m^3/h DN250 Max outlet floi have got into trouble with linear gap element. My model like flange contact have 500000 dof. i use linear gap method in axial direction and rbe2 (Fy~Mz) in other direction. unfurtunately, i just obtain some fatal message "fatal message 1012" no matter what i do. (try to change buffsize) or wirte down "nastran system (1015)=1".Happy Friday. Looking at replacing the entire bottom of a 60' diameter tank. Given the foundation configuration and some other challenges, the recommended solution is to install a second bottom over the existing bottom as specified in API 653 9.10.2.

ISZ, Thanks for the reply. I contacted the manufacturer and they recommended pointing the arrow toward the sky. The most apparent difference with the orientaion is the voltage output when the cell is loaded. If the arrow is down, the voltage is negative, if pointed up, the voltage is positive.Wind load on the superstructure may be calculated as. 150 psf x A x L. Where 150 psf is the wind pressure (Check also your state or local requirements for different criteria), A is the area of the superstructure in elevation (Curb height, slab height, haunch height, girder and any superelevation), and L is the tributary length …GEE8B (Structural) 29 Apr 23 08:33. Dead load is always downward (direction of gravity). Wind load can be upward or downward (suction/pressure). Wind forces away from the surface are (-). Wind forces towards the surface are (+). So the “W” in 0.6D+W can be negative or positive. Pressure and suction values are typically per ASCE7, and it is ...Steel Stair Seismic Design.

Includes problem solving collaboration tools. Forum. A restrained retaining wall with fixity between the footing and the stem is indeterminate. As the at-rest pressure goes to work on the stem, it's obvious that the horizontal reaction at the top of the wall will increase. If the stem and stem-footing joint are very stiff, they will significantly limit stem deflection and rotation of the stem ...In ASCE 7-22, partially open is included in those. My assumption is that they messed up and forgot to include it in ASCE 7-16.
