Place Anchor Design

CCD uses a pyramid failure surface with a slope of 35 degrees for both tensile and shear loading. The method uses formulas for tension and shear which are proportional 

Based on the above observations, this report will identify the critical steps in anchorage design and make recommendations for providing reinforcing details for safe and economical designs. 

Since the size of the concrete members in which anchors are embedded is often limited by the available space left after piping, electrical conduit, other foundations, and access requirements are met, design decisions often involve choices not required in other industries.

The objective of this committee was to update the previous report, summarizing the State-of-the-Practice for the design of cast-in-place anchor rods, welded anchors, and post-installed anchors as used in petrochemical facilities. 

Fluid power systems are designed as compactly as possible, to keep the connecting lines short. Every section of line should be anchored securely in one or more places so that neither the weight of the line nor the effects of vibration are carried on the joints. The aim is to minimize stress throughout the system. 

During the installation of FMLs, care must be taken to avoid damage from wind. Designers should determine whether wind will affect an installation and, if so, how many sandbags will be needed to anchor the FML panels as they are being placed in the field. 

Printable elements, especially those prepared by top-down methods, are often prepared such that they are attached to the mother substrate by tethers and anchoring structures that keep the otherwise freestanding elements in place. To separate elements from the mother substrate in the retrieval step, stamps must successfully break these tethers, which are typically composed of the same inorganic material as the elements. This process often requires careful design of the elements and tethers such that the elements separate by well-controlled and reliable fracture. Simple fracture theory63 points to several important factors that lead to easy fracture, notably the presence of cracks in the inorganic material and the geometry of those cracks.
