anybody having CRSI Pile Cap Design Guide soft copy plz be kind enough to share on the forum?

thanks ilyas and engruzair

If the RC wall is a shear wall rise up with the embedded column, is it still necessary??

Hi members During modelling, Is it required to model the embedded columns(modelled as frames) embedded with a RC retaining wall(modelled as a shell) or is it possible to ignore the column in the analysis and provide nominal reinforcement in the column. But since this column is required at upper levels, It will be floated at the termination level of the retaining wall in case of ignoring the frame. Please clarify which approach o be followed is correct??? Please Refer attachment. I am performing a FE analysis using ETABS Thanks in advance

Thanks Baz....

For a heavily loaded power station, A girder beam having a 500 mm set down is required to design(refer attachment). This girder is also supporting spandrel beam exactly at the set down location. The design procedure that I have followed for this non prismatic beam is as follows1. The beam is modeled using frame element as a sub frame.2. Two different frame elements are defined for the different two sections and they are combined using insertion points & thereafter loaded the beam3. Analysis results are obtained and the bottom flexure r/f are derived using the 750 mm(D) dropped section & continue through out the bottom4. Top r/f at restraint ends are also calculated for respective sections(1250 and 750 mm D) 5. Links are calculated from the analysis results at both ends for respective sections while provisions are made for the hanger links also6. The Detailing is done as given in the attachmentPlease comment if there are any more considerations on analyzing, designing and detailing to be done for these kind of beam sectionsThanks in advance

Thanks ayesha

I have a doubt that how the RC corbel action(Tie action) is applied to the RC column analysisIs it correct to applied it as a Pxav(P- vertical action on corbel, av- distance between root of corbel & line of action) or as a Tie force which counteracting the column compressive load. Consider that the RC corbel and RC column are non precast element
