These areas where ser seismic design eensaitants have etsted that the p q :::f Maliba sentainment design is Landequate, or where they have idea ified features that will require special attenties r
during final desiss(but the design at present is not in sufficient >
detail to enable fire judgementspre enumsvated below:
A. Williamson's commenta as obtained froan his report of 11/20/64:
(1) Besign is predicated en the asseption-that differential..
groust movements are not credible, therefore, verification that fealts are not prosect should be mode during escava-ties.
(pg 2)
(2) seismically induced building motimes she=1d be investigated with the effects en components somsidered. (pg 7)
(3) Vertical accelerations due to rocking should be considered in design of, equipment in the building. (pg 11)
I (4) Method of/ splicing reinforcing bars should be carefully specified.' (pg 11)
(5) Anchorage of bars in concrete is matter of critical importance for them to be able to transmit full expected loads. (pg 12)
(6) Yielding in the esposed liner indicates the need for careful specification of welding techniques. -(pg 13)
(7) Potential buckling in the exposed liner due to thermal effects of as accident indicates -the need for sufficiently small-attaabasat spacings. (pg 13)
(8) Adequacy of anchors in liners to transmit shears to the base is necessary. (pg 14)
(9) Diagemal bars included to carry shears also carry tensile loads end this should be considered in design. (pg 15)
(10) Method of analysis used in c-- -time shaar resim e=~~ -- d wLi b, compressive 1e ndings and thLs is not the core in the Malibu CN>

(11) sheer earrying espasity is apparently insuffielent et the base of the structure. (pg 18)
(12) The embedded liner is esented on to carry seisade shears and -
basis for salestaties is met eloor. (pg 19)
(13) The reinferstag around large spesings Ladioates a need for espeeditare of additiemal engineertag effort. (pg SS)
(14) Diroshinattom of vertical and horisestal effects results i
in stdeses too eloon to ytels point of the structure. (ps 21)
- 3. Newmark's report of 11/24/64:
(1) Dirset ceabiantiea ef vertieat and herisestal earthquaka offacts is demand assessary as appeeed to the proposed square reet of the sua of the squares method. (pg $
(2) Method of amshoring at the been is inadequate to devole'p stresses desired.-(pg 9)
(3) The junction of the vittiaat plate and the plate at tho' base of the structure should be shenered in a manner to enable transmission of shear forces. At present the design is imedequate. (pg 10 and pg 11)
(4) Method of anshering plates to the monarete to prevent huckling due to temperature affacte will be mesessary. (pg 11)
(5) Asinforcement requirements at the 23 feet disaster 4metration still needs additiemal work. -(pg 12)
