THE COMPRESSIVE AXIAL STRESS IN MEMBER # 1049 EXCEEDS 0.08FCK AT SECTION 0.0 MM FOR LOAD # 216 AS PER CL 6.1 OF IS-13920 2016.

Anirudh — Sun, 17 Oct 2021 04:06:34 GMT

Dear All,

I got lot of warnings for the beams that the compressive axial stress in member exceed 0.08fck. What is the solution for that i have got lot of warnings regarding this. Please suggest me

Thanks & Regards,

No member loaded for floor load generation?

Anirudh — Thu, 07 Oct 2021 19:28:53 GMT

Sir I have modelled and applied the loads in the staad interface the loads are applying but after the analysis in the output I'm getting warning that no member is loaded for the floor load generation! I have thoroughly checked the duplicate nodes,orphan nodes, duplicate members everything and I have checked the geometry of the particular nodes where I'm getting warning. Please help me in this regard

Cracked Section for concrete members

Anirudh — Wed, 23 Jun 2021 11:38:28 GMT

Dear All,

I have modelled and applied Cracked section properties code specifies Is1893:2016 and in another model i have assigned Global Cracked section properties for the beams and columns. But the results and area of steel in columns and beams are reduced in the second case compared with the code Specified Cracked Section Properties. Please clarify whether my modelling issue or any thing??

Thanks & Regards,

Response Spectrum Base Shear Scale

Anirudh — Wed, 23 Jun 2021 12:30:39 GMT

Dear All,

I have modelled and analysed a staad model with response spectrum analysis and the scale factor i have matched still im getting this. some one please clarify regarding this

NOTE : THE BASE SHEAR (VB) FROM RESPONSE SPECTRUM IS LESS THAN THE
BASE SHEAR (Vb) CALCULATED USING EMPIRICAL FORMULA FOR FUNDAMENTAL
TIME PERIOD. MULTIPLYING FACTOR (Vb/VB) ACCORDING TO 7.7.3a IS 1.0000

Axial Stress of Column Exceeds 0.4fck as per IS13920:2016 Error

Anirudh — Mon, 21 Jun 2021 07:17:55 GMT

Dear All,

Iam Designing a structure in Zone III using IS 13920:2016 in Staad Pro. Im Getting an error related to columns as

*** ERROR: THE AXIAL STRESS ON COLUMN# 46 EXCEEDS 0.4FCK FOR LOAD
COMBINATION CASE# 140 AS PER CL 7.1 OF IS-13920:2016.

KIndly Suggest regarding the error whether i have to increase the column size???

Thanks & Regards,

Story stiffness calculation in staad?

Anirudh — Thu, 03 Jun 2021 12:23:07 GMT

Hi every one i have modelled staad with same number of columns and all the column sizes are same. so as per the staad literature the stiffness of columns calculated as 12EI/L^3. My member sizes are same and the floor heights are same in staad but the story stiffness is not same. It changes from story to story pls help?

Staad Plate Element for foundation

Anirudh — Thu, 03 Jun 2021 18:33:09 GMT

Hi all Iam trying to analyse a combined footing using plate element in staad. I have modelled pedestals and applied load. But the bending moment profile is not matching with the theoritical calculations i.e., at support from the cantilever projection the cantilever moment is wl2/2 theoretically and it should be zero at the pedestal area but the plate moments are getting different and in midspan also the plate moments and shear stresses are entirely different. Please clarify

Staad Reference loads definition for soft storey checking as per indian code is 1893 2016

Anirudh — Fri, 04 Jun 2021 15:06:18 GMT

Hi all the staad reference load is necessary for checking the soft stories. But I have a doubt while defining reference loads the live load has to reduce as per the specified code or we have to assign full live load in the reference loads? Because the story stiffness is changing if it is 100% live load and if it is reduced live load. Kindly confirm whether the full live load has to define in the mass based reference load or reduced live load as per the code.

Staad Splitted R.C.C Beam Design !

Anirudh — Thu, 03 Jun 2021 08:31:25 GMT

If we model the retaining wall with attachment of beam the beam is splitting into the plate element size. How to design the multiple splitted beams in a single span is designed and analysed as a single member. Please explain.

Staad Foundation Advanced Math Processing error!

Anirudh — Tue, 25 May 2021 10:20:04 GMT

Hello all,

I have a problem with staad foundation advanced when trying to analyse and design the PileCap for the column reactions. I had a popup when starting analysis that showing an error has occurred in the script page that object doesnot support this property or method. After clicking on Yes if I analyse and design the same in the report generated file it is showing Math processing error. Could you please respond and why it is showing like that please rectify and suggest any method for that.
