Hi All,
How to calculate the short term horizontal displacement (with adopting cracked section of the concrete) on free standing wall with eccentric footing at bottom, which is subjected to wind pressure alone. This is same as calculating torque of cantilever wall.
Thank you
Dear All,
Do non-load bearing RC walls (100mm thick, 7m in Length & 3m in height) need footing? or the thickened base of grade slab is enough to distribute this self weight?? Is there any specified Code references or guidelines available?
Thank you,
Dear All,
If I define the wall as precast sandwich insulation wall panel (max thermal transmittance, U-value of 0.57 W/m2K), what could be the value of stiffness modifier to be specified in ETABS to obtain an actual behavior??

Dear All,
In Soil report, only the recommendation mentioned for isolated and Raft. In case, If I want to go for strip footing , can i use the SBC given for raft in soil report?
Thank you,
Dear All,
This is regarding the concrete column to concrete wall panel connections that to be established by L-angle as shown in Fig. below. For the same structure that're discussed in other thread Link require this connection. Both column and wall panel are precast members. I would require to...
Dear All,
What does it mean "need to check the design of tank manually as per the first principles as in staad it concentrates the moments according to nodal deflections.)
Kindly explain.
Thank you,
Dear All,
I know what is surcharge load. but how do we calculate
1. if the effect of substructure of any buildings coming near
2. if vehicle loads are considered.
Thank you,
Dear All,
Section 8 of ACI 350 states the ultimate load combinations for watertight structures design as below :
1.4D+1.7L
1.4D+1.7L+1.7H
1.4D+1.7L+1.7F
0.9D+1.7H
0.9D+1.7F

Hi all,
Anybody done Footing design using PROKON? I could not understand the calculation made by PROKON for ULS & SLS bearing pressure. It does not match with my manual cals. I just want to make sure whether my input in PROKON is right or not?
Thank you,
Prokon Input & output. Also here why...

Hi All,
Is the 'bulk density of soil' and the 'saturated density of soil' the same thing?
Which unit weight of soil (dry, saturated or submerged) to be used for Footing/retaining wall back fill calculation, in the absence of water table?
Thank u
Hi all,
How to define appropriate supports for the precast panel water tanks in Staad model? Snapshot from Staad model below shows the support defined in model. Wall unit considered as monolithic. Is this the right approach?
The precast side wall panels are stitched with cast-in-situ RC...
Hi All,
The footing size is (1.4 x 1.75)m (Fig. attached) & the SBC is 110 kN/m2
I get e> L/6 condition, Hence, I applied the 2P/BL' to calculate pressure max;
where L' is the bearing length = 3* (0.5L-e)
Thus, Qu = 2P/BL' = 102.6 kNm2
L' = 1.55 m ; P = 111.6 kN(Factored, Calculated) ;
M...
Hi All,
Can u provide me a sample calculations for earth pressure and stability check for the same.
It is a precast boundary /compound wall. Kindly refer attached sketch. Thank you...
