But i think may error dun sa last yung height ng tree which is 12m so it would be π/4•(0.6)² • (12) = 3.393m³

Structural design software use finite element analysis.

As much as possible 4 inches or 100mm lang

@@janlhesternavasca3160 thanks for reply po! may mga napapanoud kasi ako ang use nila sa special confining zone is 50mm spacing, then sa staad tutorials naman na napapanoud ko ang minimum allowed ng program is 75mm hehe

Oo yun binibigay nila pero for construction issues as much as possible idesign natin sa 100mm lang mahirap kasi lalo na pag sa may joint hirap ilagay ang rebar ng beam

So end of the day sir, kung gagawa ako ng three storey residential rcc building ano ang mas safe sa bagyo at lindol, pinned or fixed support? Salamat engr.

It was asked in the problem what if D=0.9 m

Yung green is for wind calculations. Haha challenge yung 200 mm na column pero kaya naman 😅

@@janlhesternavasca3160 sir my reference k b jan regarding sa FEA ?

Di na pasado sa SMRF yang 200mm

Thank you for appreciating

Hello, this is Euler Buckling of Column which is the basis of design codes like AISC LRFD/NSCP. Euler Stress Fcr is the Stress that will cause buckling. If FCr is greater than yielding therfore buckling will not occur since yielding is much smaller.

If based on Cc that is based on code provisions either NSCP LRFD or ASD / AISC

@@janlhesternavasca3160 ah magkaiba po b ung AISC sa NSCP?

@@nerizacullado9721 same naman. Yung Code Provisions given by AISC /NSCP 2015 ay adopted from the buckling theory of Euler. In other words sina unang way ng pagdedesign ng column yung kay Euler :)

Editted na sinama ko na AISC para wala na confusion 😄

Thank you for watching lodi sana makatulong

Hindi po, you can splice the other half dun sa susunod na floor. If not, otherwise use Class B Tension Lap Splice with, 600mm distance pa din ng dalawang na splice. Ayaw kasi natin magkaroon ng weak section

@@janlhesternavasca3160 Tama po ba splicing 50d o 40d?

@@allyce06 no, please check table of Lap Splices given in the plans. If not provided yes 40d is enough but please take not only us thus for 3000psi ONLY

Hello, from equation 1 and equation 2 using two equation two unknowns solving system of linear equations. The equations are 6.1912Fbdc + 5.2368 Fce = 960 and -4.6436Fbdc + 2.6184 Fce=0. Thank you please share and subscribe to this video. This means a lot to me :)

@@janlhesternavasca3160 Hi may I know the formula to get the lbs? Sure, thank you for replying!!

@@azixo3535 To convert KN to lbs force divide it by .00445 and multiply for vice versa.

Hello engr according to NSCP 2015 2nd printing 250mm minimum beam width

@@janlhesternavasca3160 sir may rule po ba na beam depth should be greater than 1/4 of clear span? what happens po if beam depth exceeds 1/4 of clear span?

@@chastie_6821 You can check ACI-418 sect 9.9 Deep beams or NSCP sec 409.9.9.1 deep beams na kapag ang Ln<4h therefore iba na ang way ng pag design dito you will design as a deap beam

@@janlhesternavasca3160 under ACI 418 sec 9.9 "Deep beams are members that are loaded on one face and supported on the opposite face such that strut-like compression elements can develop between the loads.." First condition nya po is that, medyo di go ma gets meaning nya, if uniformly loaded yung beam does that fall under that condition?

@@chastie_6821 no, deep beams if Ln<4h you will design it as a strut and tie method, you can also check link beams

Will do engr. stay tuned hehehe more on numerical solutions using Matlab. I'll try if I can make a video about python din.

@@janlhesternavasca3160 thanks engr.

@@janlhesternavasca3160 thanks engr.

Hahaha akala ko kung sino, thanks boss

Sige sir no problem

@@janlhesternavasca3160 ahm pwede malaman kung ano yung ASD concept , thank you po sa pagreply sa akin

Hello, as for the joint tie zones, ACI and Industry standard limits to 100mm spacing on JOINT tie zone (see example Seismic Design of Reinforced Concrete Special Moment Frames, section 5.3) and we should check its joint shear capacity.

Thank you Engr. for your appreciation 😊

That is for non seismic detailing. The spacing requirement are based from the required shear Vs carried by the ties.

That is maximum spacing for Non seismic detail column
