@@preciousliamb.d9532 just use your calculator functions either the shift solve mode, quadratic eqn (degree of 2), or by manually simplifying the equation using discriminants rule learned from your algebra class. Cheers

hi. baka yung tinatanong mo yung sa integration is bakit 6 yung denominator? it is not the span. it is a constant based on derivation bago mo iapply sa (6/L)(A1a1). Cheers. for clarification check this video lecture for derivation: ua-cam.com/video/M8Sl6XDcu2U/v-deo.htmlsi=TMxJbW_dCvtLNdZ-&t=1536

@@josephjoe9525 use geometric reorientation for those loads not touching the fixing point and loads which is 1st deg or higher should be increasing as it approaches the same point. Cheers

@@mmrida_ hi see the principle of derivation. See my discussion in my playlists. Cheers.

hi. if you have a stick model beam analysis (support as drawn like hinge or roller or fixed just like without size of support column) it will look like a center to center position since you dont have a basis where the support face is since no dimensions of support are given. cheers

@ eyy thank youuu, but pag meron namang dimensions ang support then consider ko yung d distance @ face of support?

@@TERENCEKLYNDIAMANTE yes measured from the face (either exterior or interior face) of support (column or spandrel)

@@nioroskyengineeringonline8968 sir same value lang din ba kahit yung loading patterns ang gamitin sa pag solve ng vu?

@@TERENCEKLYNDIAMANTE as chapter 2 considered.

@@jmonster4964 yes. Derived from 2.4x9.81

hi sir. it was mentioned to measure from the face of the support up to the midspan for seismic design requirement. Dont forget that the critical spacings of stirrups are found nearest to the support. distance "d" are for initial analysis to be proven later since spacing of stirrups also adjust not exactly the same as "d" value. Cheers :)

Vu are found nearest to the support which is within the "d" region when measure from the face of the support. Cheers

Note that as per calculation, there is a need to use 8-175mm stirrups that is 1.275 m distance which is higher than "d" :) please refer to the prior calculations before this video lecture. refer to my playlists or proceed to this link: ua-cam.com/video/HwGm3uTpWfc/v-deo.htmlsi=FnH7dcw-3cDMx-hH&t=2430

Di yan ma check nmn yan sa stress strain diagram ahahahaha

understand that ductile failure mode is the ultimate aim of any civil engineer. this will permit evaluation of impending failure and building inspectors could decide condemning/ demolition for safety reason. Having over-reinforcement shall mean destructive and sudden failure of structure which is unsafe for any unknowing building occupants.

@russell2514 tnx sir

@russell2514 no worries wala pa ako na design na bahay xD

@russell2514 pag aralan ko ductile failure kong ano yun, sa rcd plng medyo gamay ko

Yong ductile failure yan ba yung lalampas sa C ang compresiv area ng strain diagram? Where C=beta1 a

Yun din ang tanong ko hmm. Since wala naman part ang assumed 300mm sa equation right?

Hi as mentioned in the video, nscp 2015 sections was mentioned.

Yes. The full detail of seismic detailing requirement are soon to be uploaded.

Hi check again the units. Note that the area moment diagram by parts has units of KNm. And the unit of deviatoric distance is kNm^3, not mm before dividing to EI since it has a unit. Cheers. Review your dimensional analysis.

Note that i used the unit RI in terms of Nmm^2 so there is a need to convert the numerator by 1000^3 to convert kNm^3 to Nmm^3. So Nmm^3/Nmm^2 is mm which is our desired unit of displacement as a deflection :)

Congrats engr :)

For upload pa in the future

Ok lang yan. You can read books as main material for reference which is dun ko din binase discussions ko. Cheers.

Hi. If you are asking for dimension assessment its qult first since how can you get qnult if you dont have the size of footing to deduct as an effect of stress to be transferred on the footing itself :) also as set forth in section 413.3.1.1. Cheers

Also by logic, is it right qna is greater than qult whereas qult is the factored stress? Note that qult is the magnified value of stress and qna is the net condition lower than qult due to deductions of stresses transfered from generated stresses above.

@@nioroskyengineeringonline8968 I'm just wondering that the paired equations for q_ult would be q_all and if net would be qn_ult and qn_all. Then basing with NSCP it is not how it should be paired. Anyway, just confirming things. Thanks

@@engineersspace2024 for direct basis, see any reference book authored by braja das or muni buddhu. Cheers.

@@engineersspace2024 @norielepaulcruz3242 q ult is the reference since we are approximating bearing resistance based from forces that understand service state conditions. Note that it is set as a min condition for approximating sizes of footing then note for final checking the qna was taken to assess proper stress where stress of soil was deducted to q ult since size is determined as shown in 1:29:33 for final checking.

As explained, crack is under service state.

@@nioroskyengineeringonline8968 maraming salamat po sir

s ir reference book nyo sa problem na yan?​@@nioroskyengineeringonline8968

nvm, so 1000 para sa kN to N and another 1000 from meter to mm

As discussed in NSCP and AISC, MP is observed under nominal condition. Please refer to my first set of video lectures found on this playlists
