Shear Lug Design - Overview of the ACI Provisions


Shear lugs are steel elements welded to the underside of base plates to resist shear loads. The design of shear lugs may be time-consuming since it included the check of a number of limit states per the ACI 318-19 anchoring provisions.

But why do you need to design a shear lug? And if you need it, how do you design it? What are the limit states to be checked? Are there any additional dimensional requirements?

I have prepared a blog post with a short video with a brief overview of the new requirements for shear lugs in the latest ACI 318 anchoring provisions, using ASDIP STEEL as the supporting tool. Your comments and suggestions are always welcome.

What You Must Know About Concrete Foundation Anchor Bolt

An anchor bolt is an essential element in the structural construction field. The primary element of anchor bolts is to move loads from an anchor (ledgers, sills, and plate bearings) to the masonry. A robust anchor bolt design allows both shear transfer and pressure to withstand construction forces. This is used to connect objects or constructs to material, to put it in plain terms. Various types of anchor bolts can be found on the market today, which consists mostly of variants that are largely unique to the manufacturing company. You can find a hooked end in most of the designs, connected to which is about being a nut and a washer. They can be of assistance to external loading. In a range of economic projects, anchor bolts are widely common, from traditional frameworks to dams and nuclear energy projects.

It is a known fact that even a minute discrepancy in measurements of steel structural engineering can lead to major failures. A lot of money goes into such engineering projects. Apart from money, hours, days of energy is too invested in them. If mistakes or errors begin to take place, both energy and money will get wasted, which is something no construction or manufacturing company wants. This is why using a top-quality steel structure software becomes important. Features of ASDIP STEEL 5 are being talked about online as this software is expected to be one of the best steel structure software in the market. What are the reasons behind its popularity? Let’s find out. l         Softwares of this type are made in such a way that they comply with certain data pertaining to building plans. If engineers use such a software, then incidences of errors and structural failure would go down considerably. Contractors will be able get their desired results l     ...

Pile Cap In Constructions and Designs

What Are Pile Caps? Pile caps are thick reinforced concrete maps that tend to rest on top of concrete or wooden piles to offer good stability to the foundation. So, the primary purpose of the construction of the  pile caps  is to distribute the load of the column, which seems to be significant for large constructions. The exact dimensions of the pile caps are determined by the loads and strategic arrangement of the methodology of the structure and foundation. The shape of the pile cap is observed and calculated by the number of piles within the group and the very spacing between each one of the piles.  The function of a Pile Cap: To evenly distribute a single load emerging from the column to the piles.  Further, stabilizing the pile, resulting in the overall efficiency of the pile group. Providing the joint resistance stresses established by the superstructure along with the ground movement.  Considerable Features ...
