If it is an intermediate support and if the beam is continuous over it, then it is something between hinged and fixed. Basically it is called a continuous beam and you can use different techniqes to calculate shear, moment, deflection for a continuous beam (e.g. moment distribution, slope...
You should indicate on the project drawings/specifications that "the welding of reinforcing bars shall conform to the ANSI/AWS D1.4 Welding Code." ANSI/AWS D1.4 requires the Contractor to prepare written welding procedure specifications conforming to the requirements of the Welding...
You can bolt narrow steel plates (say 1/2" thick and 6" wide) to one or both faces of the CMU wall (depending on the loading condition). If steel is attached to both faces, through bolts are the best way of attaching them, else use masonry epoxy anchors. Anchorage shall be done in...
You may want to consider reinforcing the wall externally by applying carbon fiber strips or even steel bars/plates to the face of the wall without cutting the cells open and without need for grouting.
If you have a short column and the load is applied exactly along its longitudinal axis, then the failure happens when yielding occurs. Therefore your failure load is P=A*Fy (area times yield strength).
However, a long and slender column under a concentric load will fail due to buckling before...
A point of inflection by itself does not provide for a bracing point agianst LTB (lateral torsional buckling). A good discussion on this issue can be found in MODERN STEEL CONSTRUCTION January and November 1997 issues.
Note 3 at the end of the Table in Section 16 reads: " For locations not designated as a county, use basic wind spped for the closest county to the site."

I assume that you are investigating this existing structure to renovate it. The question of whether the renovated building shall conform to te requirements of the code for new construction is far from clear. The local building official should be contacted to establish the degree of...
I should add a few more words to my previous response. One should not confuse the 5000 lb OSHA requirement for personal fall arrest systems with end anchor capacity requirements. In fact, after applying the load magnification factor and the minimum safety factor of 2.0, in most cases, the 5000...
While installing a flexible horizontal lifeline is as simple as stringing a line between two anchor points, it is one of the most complex types of fall protection systems when it comes to designing it. Design issues to be considered are:
1. The Load that is applied to the anchor points during...
Does anybody know why the grinding chamber of the Netzsch grinding mills do not have an ASME nameplate? It operates at elevated temperature and pressures and appears to fall under ASME Section VIII, Div 1 requirements. Any feed back is greately appreciated.

While the free end of the cantilever can warp, the fixed end of the cantilever beam is prevented from warping. Such nonuniform warping results in additional shearing stress that should be accounted for. Therefore, additional warping stress shall be added to (torque)*C/J suggested by drgeers...

A very good source of information is the ASCE Publication "Wind Loads and Anchor Bolt Design for Petrochemical Facilities". It has good discussions and design examples for Open Framed Structures.
