Hi to experts,
I have a question regarding Rebar Details of a long span continuous beam which our engineering deapartment submit a shop drawing which does not conform to ACI typical beam rebar detail because only 12.0m in length of rebars are available in the market. However, in ACI, it is...
Hello everybody,
I have deep foundation located near the area where water table level is more or less 1.5m from ground surface. A pile cap is to be constructed at a deep as the same level of that water table. My concern is, I could not completely keep the the water down below the bottom of...
Good day everybody,
I have some concern regarding adding super plasticizer at site just before discharge of ready mix concrete. Our footing designed with lot of rebars so we need a flowable concrete for workability. Our mix design includes plasticizer and retarder admixtures but when arrived at...
I have columns with congested rebars and tie bars. I'm planning to order a ready mix concrete with slump of 125 +/- 25mm. Our mix design is 35 MPa with max aggregate nominal size of 19mm with water-cement ratio of 0.42. What is the acceptable max slump for column? Please any expert on concrete...
What is the reason behind in excluding live load from calculating base shear for seismic load of a building? Any expert, please share your opinion on this based on IBC, UBC or any applicable codes. Thank you so much.
I just started splicing rebars of column and found out that the rebar length is 6.65m and the available full length is 12.0m. So I just cut it into two so that the rebar to be spliced will be 6.0m only which is short by 65.0cm. So I want to offset the splice from the center by 65.0cm upward to...
Our QC inspector requires us to remove the wet and loose soil which is present after excavation for footing to be supported by bored piles. As we can see in the site, the foundation level is below water table and it is not possible to compact the soil with required 95% compaction. Is it...
To all experienced construction engineers,
Our contractor wants to place the construction joint of ramp beam at the face of column support due to work difficulty if it is done monolithically. Is it safe to place the joint at the face of support? What provisions to be made if such joint is...
The contractor is insisting that Ld formula for tension is not applicable in columns because by doing it so, lapping is excessive for rebars with dia 32mm size. Our design department clearly specify that lapping shall be at mid height with tension splice of 1.3xLd. So that will make the lapping...
Please post the formula of Ld of rebars of vertical structural elements as per latest ACI CODES.Which formula of Ld in tension or compression to be used.Thanks a lot elements
