Hi everyone, I am trying to design masonry shear wall. My reference is "Reinforced Masonry Engineering Handbook-6th Ed." by Amrhein. Can anyone please tell me what is the difference between the example 6-I and 6-J? Why are they analyzed differently?The PDFs of the examples are attached...
Hi all,
I am working on a structure that has tow low roofs surrounding a middle gynasium which is a separate higher roof. The average height of low roof is 14' and that of higher roof is 21'.
While caculating the ASCE MWFRS wind load using directional method, what do you guys use as 'Mean Roof...
I know I posted this question in other forum. But I didnt get much reponse. So I am reposting it again.

Suppose you have a very long wood shear wall. In reality, the long shear wall is divided into a number of panels at shop for installation at site. How do you guys analyse the overturning of shear wall for chord forces and hold down design? Do you divide and analyze the walls separately or do you...
Hello everyone,
How everyone is designing the column cap plate for beam bearing over the top for different connections like simply supported, continuous beam over the top without moment transfer to column and even with moment transfer? I couldnt find anywhere the actual design process. Is it...
Hello everyone,
I was wondering how everyone assumes the prismatic strut and bottle-shaped strut in Strut and Tie Design. For example, jn a beam, do you assume the horizontal strut as prismatic strut and the diagonal strut as bottle-shaped strut? Or is there any other logic involved. Thanks.
Hi, is there any requirement in ACI-318 for minimum bars to be used in the top in singly-reinforced beam? I know we use longitudinal rebars at top to hold stirrups. However, I couldn't find any section in ACI for the size of bars to be used. Can we use any size bar or is there any minimum...
Hi,
I have an existing beam that needs to be reinforced for additional loads. For flexure, I have added top and bottom plates. However, for shear strengthening, I need to add transverse stiffeners. When I look into AISC 15th Ed. Manual section G2.1(a) for rolled I shaped members, it doesn't...
Can someone please refer me to some design examples on how to design a column cap plate above a wide flange column? A WF beam is resting on the cap plate and is simply connected to it. I can't find anywhere regarding the design of cap plate.
Thanks.
Suppose you have two bay frame in which the two beams are connected to column in the middle through moment connection. The beans are also connected to end colums through moment connection. Do you analyze this beak as a simple continuous beam? Does the moment connection makes the beam continuous...
I have a steel resting on a concrete Pier/ Pedestal. Is the two Pier/Pedestal same? OR is there any difference? Also what design approach should I use to design it? Should I just design it as a concrete column?
Thanks.
Do we need to consider any amount of minimum seismic load and wind load for gravity only elements? I have a podium building with steel braced frames on the first floor. Do we only consider seismic/wind forces for the foundation design of braced frames or do we need to consider it for other...
Hi all,
I know that in rigid diaphragms, we distribute the seismic force (which is applied at the CM of diaphram) based on relative stiffness of the vertical elements. However, I find examples of shear wall only in each and every book. I am not sure how to distribute seismic forces in moment...
Hi, I am a junior structural engineer. I want to know what is the difference between normal wood wall and wood shear wall. While modeling in RISA, do we consider all the walls as lateral walls even if we will be using only some walls as shear walls.
